Some prepositional verbs can also be used without any preposition before their object noun – but usually with a different meaning
THE NATURE OF PREPOSITIONAL VERBS
Prepositional verbs include both a verb and a preposition. The preposition is a true one, unlike in “phrasal” verbs where preposition-like words are actually adverbs (see 139. Phrasal Verbs). Sometimes there is a noun in the middle (see 123. Prepositional Verbs Containing a Noun), but verbs without one are the focus here. An example is DEPEND ON in sentences like this:
Here the verb is not depend but depend on. The preposition on is part of the verb, and sunlight is the object of this verb (for details of objects, see 8. Object-Dropping Errors).
Not all prepositions are part of the verb before them. Consider into in this example:
(b) The River Nile flows into the Mediterranean Sea.
Here the preposition into is combined with the words after it rather than the word before, creating an adverb-like phrase. As a result, the verb flows is intransitive, lacking an object (see 113. Verbs That Cannot Be Passive). Linguists have some ways of deciding which use a particular preposition has, but I will not go into those here.
Prepositional verbs like DEPEND ON have various interesting features. Some of these are considered elsewhere in this blog in the posts 31. Prepositions after Action Nouns 1, 35. Words Followed by “to -ing”, 42. Unnecessary Prepositions and 108. Formal and Informal Words.

THE PROBLEM OF VERBS USABLE BOTH WITH & WITHOUT A PREPOSITION
Some prepositional verbs can cause confusion through being able to drop the preposition before a following noun in order to express a different meaning. The verb APPROVE is of this kind; consider the change of meaning in the following sentence if of is removed:
(c) The committee approved of the proposal.
The meaning of the prepositional approved of is “liked”, while that of non-prepositional approved is “allowed” or “passed”.
Note how both sentences have the same object (the proposal). This is an important aspect of the verbs in question. Some verbs that can be used both with and without a closely-linked preposition have to drop their object without the preposition. For example, if we change LOOK AT into LOOK, an object is not possible – LOOK by itself is intransitive. This discussion is not about verbs like LOOK (I cannot say for sure that such verbs are less problematic, but my experience suggests they are).
A likely result of confusing the two uses of verbs like APPROVE is that the preposition will be either wrongly added (see 42. Unnecessary Prepositions) or wrongly left out.

TRANSITIVE VERBS USABLE BOTH WITH & WITHOUT A PREPOSITION
English has quite a lot of verbs like APPROVE. Below is a sample (the abbreviations “sb” and “sth” stand for “somebody” and “something” respectively). It may be useful to try and either guess the meaning differences or discover them from a dictionary. Some of the more problematic meanings are explained below.

EXPLANATION OF SOME ESPECIALLY PROBLEMATIC PREPOSITIONAL MEANINGS
Rather than just list the meanings in question, I offer a matching exercise. The reader is invited to match each definition below with the right verb from the list before it (answers after the exercise).
.

.
ANSWERS: 1(a) = agree on, 1(b) = agree, 1(c) = agree to, 1(d) = agree with; 2(a) = conceive, 2(b) = conceive of; 3(a) continue, 3(b) = continue with; 4(a) = decide, 4(b) = decide on; 5(a) = enter into, 5(b) = enter; 6(a) = improve; 6(b) = improve on; 7(a) = report, 7(b) = report to, 7(c) = report on; 8(a) touch, 8(b) = touch on; 9(a) = join in, 9(b) = join; 10(a) = know about/of, 10(b) = know.
Noteworthy in the above sentences is the similarity of on after AGREE and DECIDE (#1A and #4B). For more about DECIDE ON, see 276. Tricky Word Contrasts 11, #5.
.
VERBS WITH AN OPTIONAL PREPOSITION
Some verbs can be used either with or without a preposition yet keep the same meaning. They are not problematic in the same way as the verbs discussed above. Usually their non-preposition use is simply a more modern preference. Five common examples of verbs like this are PROTEST AGAINST, APPEAL AGAINST, DEPART FROM, DISEMBARK FROM and IMPACT ON:
(d) Drivers are protesting (against) the new law.
(e) The company will appeal (against) the guilty verdict.
(f) The new law will impact (on) traffic volume.
.
VERBS THAT OCCUR BOTH WITH AND WITHOUT A FOLLOWING ADVERB
Some verbs look to be prepositional but are not. Examples are CUT OFF, PICK UP and FIND OUT. The second word in each of these is actually an adverb: it can be placed after the verb’s object just as adverbs can. For a full explanation, see 139. Phrasal Verbs. A typical phrasal verb use might be the following:
(g) One cannot write everything down in a lecture.
I mention phrasal verbs because they present a problem that is similar to the one with prepositional verbs: learners of English often confuse the meaning of the verb by itself with that of the verb and adverb combined. Here are some example pairs:
BREAK sth BREAK sth UP
CLOSE sth CLOSE sth UP (DOWN)
CUT sb/sth CUT sb/sth UP (DOWN/OFF/OUT)
DROP sth DROP sb/sth OFF
EAT sth EAT sth UP
FILL sth FILL sth IN
FIND sb/sth FIND sth OUT
MISS sb/sth MISS sb/sth OUT
OPEN sth OPEN sth UP
PICK sb/sth PICK sb/sth UP
SEEK sb/sth SEEK sb/sth OUT
SELL sth SELL things OFF
WRITE sth WRITE sth DOWN
RISE (intransitive) RISE UP (intransitive)
To give a flavour of the differences, FILL means “change from empty to full” whereas FILL IN means “add material to visible spaces until they no longer exist”. We particularly use FILL IN with forms and shapes.
FIND and FIND OUT can both mean “discover hidden information”, but out suggests the use of much effort, often because the information was deliberately hidden.
PICK means “choose” or “remove from the plant where it grew” (e.g. picking flowers or grapes); while PICK UP means “lift to take possession of” or “take into your vehicle for transport”. It is notable that PICK by itself is used in both East and West Africa with all of these meanings.
WRITING DOWN is done when we want something to be remembered; WRITING is done for any other purpose.
Finally, RISE means “go up”, while RISE UP means “start a war of rebellion”.
