A verb’s meaning sometimes shows whether or not it can have an object and “to” verb
THE USE OF OBJECT + INFINITIVE AFTER VERBS
English quite often needs the object of a verb to be followed by the to form (infinitive) of another verb. However, such combinations are not all the same. Compare:
(a) Businesses need customers to support them.
(b) Businesses need customers to supply.
(c) Businesses need customers to grow.
Customers in all of these is the object of need. In (a) it is simultaneously the subject of the subsequent verb support (they do it), whereas in (b) it is simultaneously the object of supply (they receive supplies). In (c) customers is neither the subject nor object of the subsequent verb grow (businesses is the subject and there is no object).
This post is about combinations like (a), where a verb’s object is the subject of a subsequent infinitive. The object and infinitive must be equally affected by the first verb’s action: it is not customers in (a) that businesses need but their support (for an illustration of less-affected infinitives, see sentence #h in 239. Nouns Combined with a “to” Verb). The problem with situations like (a) is that the second verb sometimes needs another form than the infinitive, particularly -ing.
The choice between to and -ing after an object often depends on the choice of first verb. INVOLVE is one requiring-ing (see 232. Verbs with an Object + “-ing”). NEED actually allows either to or -ing, enabling its action to seem complete or ongoing. Many verbs, however, allow only to.
This variability of verb properties means a knowledge of infinitive-allowing verbs is necessary in order to prevent incorrect to/-ing choices. Helping to meet this need is the particular concern here.
.
THE VARIABILITY OF ENGLISH VERB GRAMMAR
Before viewing the relevant verbs, consider the following variety of dependent structures that are possible after active verbs in English. No verbs allow them all; most allow only one or a few.
1. NO EXTRA WORDS (e.g. increased)
2. VERB + OBJECT (e.g. increased prices)
3. VERB + ADJECTIVE/NOUN COMPLEMENT (e.g. was difficult/a problem)
4. VERB + INFINITIVE (e.g. needed to know)
5. VERB + -ing VERB (e.g. kept going)
6. VERB + CONJUNCTION… (e.g. thought that they succeeded)
7. VERB + OBJECT + OBJECT (e.g. showed everyone charts)
8. VERB + OBJECT + COMPLEMENT (e.g. made everyone happy)
9. VERB + OBJECT + as + COMPLEMENT (e.g. saw it as a threat)
10. VERB + OBJECT + to VERB (e.g. caused something to happen)
11. VERB + OBJECT + -ing VERB (e.g. saw someone running)
12. VERB + OBJECT + PREPOSITION (e.g. took note of…)
The pattern(s) allowed by a particular verb cannot be reliably identified from its meanings. The verbs CEASE and STOP, for example, are similar in meaning and in both allowing #1, #2 and #5 above, but the former also allows an infinitive (#4), the latter an object + -ing (#11) (see 250. Synonym Pairs with Contrasting Grammar, #2). CRITICISE, despite being a speech verb, does not allow #6, instead requiring #9 or #12 (see 279. Grammatical Variability of Citation Verbs).
The relevant pattern here is #10. If the verb is passive, with its object as its subject, the infinitive usually follows it directly (see 299. Infinitives after a Passive Verb, #1).

.
VERBS ALLOWING AN OBJECT + INFINITIVE
The relevant verbs can be classified according to their meaning. Verbs with “cf.” below can change their meaning and hence meaning group.
1. Commanding
ASK (cf. “requesting”)
CHARGE
CALL ON
COMMAND
CONDEMN
DIRECT
FORBID
INSTRUCT
ORDER
REMIND
REQUIRE (cf. “needing”)
TELL
WANT (cf. “desiring”)
WARN…not…
WOULD LIKE (cf. “preferring”)
Verbs like these are commonly said to introduce “indirect commands” (see 150. Verb Choices with Indirect Speech). Many involve the idea of “must” (see 65. Verbs that Mean “Must” or “Can”).
Indirect commands may be reported or non-reported:
REPORTED: X asked (is asking) Y (or you) to…
NON-REPORTED: I ask you to…
Commands reported with WOULD LIKE must be current at the time of reporting (like commands after is asking above) – WOULD LIKE has no past form. Starting with I or we is typical of non-reported indirect commands (see 238. Using a Verb to Perform its Action).
Infinitives after the object of a command verb mean the command must be carried out by the person(s) expressed by the object. Commands for other people need that… after their object. TELL allows its object to be repeated after that (told X that X should…), but only for advising (see 217. Tricky Grammar Contrasts 1, #4).
Some commanding verbs – e.g. DECREE, DEMAND and PROHIBIT – cannot have an object + infinitive. The error of giving them one could result from the existence of so many verbs with similar meaning that allow it (see 10. Words with Unexpected Grammar 1).
.
2. Requesting
APPEAL TO
ASK (cf. “commanding”)
BEG
BESEECH
CALL ON
ENTREAT
INVITE
NEED (cf. “needing”)
REQUEST
WISH (cf. “wanting”)
WOULD LOVE (cf. “needing”)
These verbs with an object + to either make a request (I ask you to…) or report one. NEED and WISH respectively express “needing” and “wanting” instead of requesting when in past tenses. For more about WISH, see 254. Tricky Word Contrasts 10, #6.
ASK, BEG, WISH and WOULD LOVE can also drop their object so the request is for their own subject to perform the infinitive verb’s action (see 302. Verbs with a Partner Infinitive).
PRAY mostly uses that… instead of object + to….
.
3. Persuading
ADVISE
*COAX
*CONVINCE
COUNSEL
DARE
ENCOURAGE
*MOTIVATE
*PERSUADE
PRESS
*PUSH
URGE
These verbs form the third major group commonly associated with indirect “commands”. Those marked * can only report persuasion; the others can also assist it.
DARE and PUSH can drop their object. For more on DARE, see 148. Infinitive Verbs without “to”.
For a discussion of URGE, see 195. Tricky Word Contrasts 7, #1.
Persuasion verbs with different grammar include ARGUE, RECOMMEND and SUPPORT. For details of RECOMMEND, see 187. Advising and Recommending.
.
4. Needing
COUNT ON
DEPEND ON
NEED (cf. “requesting”)
RELY ON
REQUIRE
TRUST
All of these except TRUST allow -ing after their object as well as to: -ing highlights continuation within the event, to the overall event (see 232. Verbs with an Object + “-ing”). Need verbs that disallow an object + to include CRAVE, HOPE and INVOLVE.
NEED can also have just a following infinitive, or an -ing verb with passive meaning (see the end of 83. Adjectives before a “to” Verb). For other aspects of NEED, see 129. Differences between Necessity Verbs and 148. Infinitive Verbs without “to”. For details of REQUIRE, see 292. Synonym Pairs with Contrasting Grammar 2, #5.
.
5. Desiring
*DESIRE
*HOPE FOR
LIKE
LONG FOR
LOVE
PREFER
WANT (cf. “commanding”)
*WILL
*WISH (cf. “requesting”)
WOULD LIKE (cf. “commanding”)
*WOULD LOVE (cf. “requesting”)
YEARN FOR
Many of these allow -ing after their object as well as to (* shows exceptions). All except HOPE FOR, LONG FOR, WILL and YEARN FOR also allow a lone infinitive. PREFER allows that… as well, while LOVE and LIKE can have it that… (see 190. Special Uses of “it”).
Want verbs that do not allow an object + to include APPRECIATE, ENJOY, CRAVE, HOPE and negative REFUSE. For more about the first two, see 10. Words with Unexpected Grammar 1, #b.
.
6. Anticipating and Planning
AIM FOR+
ARRANGE FOR+
*EXPECT
HOPE FOR
*INTEND
*MEAN
PLAN FOR+
*PREPARE
PRIME
TIP
TRUST
WAIT FOR
In addition, FORECAST, FORESEE and PREDICT allow to be (but no other infinitive) after their object.
ANTICIPATE and ENVISAGE need -ing or that… after their object instead of to…, and FORECAST, FORESEE and PREDICT do too when not combined with BE (see 242. Words with Unexpected Grammar 3, #d). In the passive voice, however, all these verbs need to.
Verbs marked * also allow an infinitive without an intervening noun; + indicates a choice between to and -ing. For more on AIM and INTEND, see 114. Tricky Word Contrasts 3, #5.
.
7. Causing
*ALLOW
ARRANGE FOR
*ASSIST
*CAUSE
COERCE
*COMPEL
ENABLE
*FORCE
HAVE
*HELP (cf. “teaching”)
IMPEL
*INDUCE
LEAD
LEAVE (= allow by freeing or not stopping)
LET
MAKE
*PERMIT
*PROMPT
*REQUIRE
*STIMULATE
About 50% of cause verbs allow an object + infinitive. HAVE, LET and MAKE must drop to from the following infinitive (see 148. Infinitive Verbs without “to”), while HELP allows a choice. None in the list can have a lone infinitive, but those marked * can have just an object.
For cause verbs that need an alternative construction – e.g. ENTAIL, FACILITATE, LEAD TO and MEAN – see 32. Expressing Consequences.
Note the absence of STOP from the above list. To name a stopped action, the verb after STOP’s object needs -ing, not to (see 250. Synonym Pairs with Contrasting Grammar 1, #2). Using to is a common error. It is only correct for expressing a purpose of STOP’s subject. For example, X stopped the film to explain means X intended to explain.
.
8. Recruiting
APPOINT
CHOOSE
CONSCRIPT
DECREE
ELECT
NAME
NOMINATE
RECRUIT
All of these are alternatively usable with an object complement (noun or adjective after their object: see 220. Features of Complements). NAME above means “decree”. For how this differs from NOMINATE, see 236. Tricky Word Contrasts 9, #2.
.
9. Believing (mainly with to be/have)
ACKNOWLEDGE
ASSUME
*BELIEVE
*CONSIDER
DENY
ESTIMATE
EVALUATE
FEEL (cf. “sensing”)
*FIND (cf. “sensing”)
FORESEE
FORECAST
GUESS
HOLD
IMAGINE
INTERPRET
*JUDGE
KNOW
PERCEIVE
PICTURE
PREDICT
PRESUME
REGARD
SEE (cf. “sensing”)
SUPPOSE
TAKE
*THINK
UNDERSTAND
VIEW
VISUALISE
It needs to be emphasised that the only infinitive forms possible after an object of these verbs are to be and to have, with that necessary otherwise, e.g. …assume that X works.
Verbs marked * can drop to be altogether (transforming what follows into an object complement). A few others, such as TAKE and UNDERSTAND, allow as instead (though with TAKE the meaning changes: see 264. Variations in the Use of TAKE, #16). SUPPOSE sometimes changes its meaning when passive (see 81. Tricky Word Contrasts 2, #3).
Belief verbs that do not normally allow an object + infinitive include AGREE and DISAGREE.
.
10. Establishing (mainly with to be/have)
*DECLARE
DEFINE
*DEMONSTRATE
*ESTABLISH
IDENTIFY
*IMPLY
PAINT
PORTRAY
*PROCLAIM
*PRONOUNCE
*PROVE
RECOGNISE
*SHOW (= prove)
Again, a following infinitive is typically to be or to have. Verbs marked * allow that + BE instead; the others allow as + noun (see 92. Verbs with an Object + “as”) or as -ing.
Verbs like the above that cannot have to – preferring as instead – include CRITICISE, DESCRIBE (usually), THINK OF and TREAT.
11. Teaching
COACH
HELP (cf. “causing”)
TEACH
TRAIN
Among other teaching verbs, EXPLAIN needs especial care: its object must be the explained idea, not the addressee, and any naming of the addressee must be after the preposition to: EXPLAIN (something) to (someone). The only way to include an explained action is with how… – see 140. Words with Unexpected Grammar 2, #b.
EDUCATE, SHOW, TUTOR and non-commanding INSTRUCT and TELL all need the addressee as their object like TEACH, but no following infinitive. SHOW and TELL can add either a second noun or indirect speech, especially questions with a to verb (…showed X how to…). The others often have in + noun, e.g. INSTRUCT (someone) in (something).
.
12. Sensing
FEEL (cf. “believing”)
HEAR
LISTEN TO
NOTICE
OBSERVE
SEE (cf. “believing”)
SENSE
SMELL
WATCH
An infinitive after the object of these verbs cannot have to. Note, though, that to becomes necessary (with be or have) after FEEL and SEE when they mean “believe” (see 217. Tricky Grammar Contrasts 1, #6).
If the infinitive after the above verbs is passive (e.g. …saw X be given help), be can be dropped along with to (see 192. When BE can be Omitted, #4).
An alternative to the infinitive after sense verbs is an -ing form highlighting the continuousness of the event (see 148. Infinitive Verbs without “to”, compulsory use #2).
