Determine whether the verb 'allege' is ditransitive and analyze the grammatical function of the infinitive complement in a passive construction. | Step-by-Step Solution
Problem
Is the verb 'to allege' ditransitive? The student questions whether 'to allege' is ditransitive, noting that in the sentence 'he is alleged to have seen him,' the infinitive phrase 'to have seen him' appears to function as an object, which would suggest ditransitive behavior.
🎯 What You'll Learn
- understand the distinction between different types of verb valency
- analyze how passive voice restructures argument patterns
- recognize that surface structure may obscure underlying argument roles
Prerequisites: understanding of transitive and ditransitive verbs, knowledge of infinitive phrases and their functions, familiarity with passive voice constructions
💡 Quick Summary
Great question — this touches on some really fascinating territory in English syntax! Before jumping to a label like "ditransitive," it's worth pausing to ask yourself: what exactly does ditransitive *mean*, and what would a verb need to look like in order to earn that description? Think about a classic ditransitive verb like *give* — what kinds of arguments does it take, and how does that compare to what *allege* seems to want? It might also help to try constructing an active version of your passive sentence and ask yourself what *allege* is really selecting for — is it selecting a person, a proposition, or something else entirely? Once you've thought about that, consider what might be happening to the subject of the infinitive phrase when we move from the active to the passive — could there be a "raising" process at work that makes the sentence *look* more complex than the underlying argument structure actually is? You're already thinking about this in exactly the right way, so trust your instincts and see where that analysis takes you!
Step-by-Step Explanation
TinyProf's Grammar Breakdown 🎓

1. What We're Solving
You're asking whether 'to allege' is ditransitive, using the passive sentence "he is alleged to have seen him" as your evidence. Let's unpack what's really going on here!
---
2. The Approach
To answer this, we need to work through three building blocks:
- What does "ditransitive" actually mean?
- What arguments does 'allege' actually take?
- What is the infinitive phrase really doing in that passive sentence?
---
3. Step-by-Step Solution
Step 1: Recall What Ditransitive Means
A ditransitive verb takes two objects simultaneously:
- A direct object (the thing affected)
- An indirect object (the recipient)
Both objects are noun phrases, and crucially, they represent two distinct participants in the event.
---
Step 2: Identify What 'Allege' Actually Takes
Looking at how 'allege' behaves in active sentences:
> "They alleged that he had committed fraud."
Here, 'allege' takes:
- ✅ A subject (they)
- ✅ A complement clause as its object (that he had committed fraud)
> 💡 You allege a proposition — a claim about the world — not someone or something a proposition.
---
Step 3: Examine the Passive Sentence Carefully
> "He is alleged to have seen him."
This is a raising construction. Let's decode it:
The underlying active structure is: > "They allege [that he has seen him]."
When this is passivised, English raises the subject of the embedded clause (he) to become the grammatical subject of 'allege':
| Stage | Sentence | |---|---| | Active | They allege [that he has seen him] | | Passive (clausal) | [That he has seen him] is alleged | | Raising passive | He is alleged [to have seen him] |
So 'he' is not a true object of 'allege' in meaning — he is the raised subject, and the infinitive phrase is the remnant complement.
---
Step 4: Is There a Second Object?
For 'allege' to be ditransitive, we'd need: > ❌ "They alleged him a liar" (not standard English) > ❌ "They alleged her the facts"
These don't work! You can't give 'allege' both an indirect object and a direct object in the way you can with give, send, or tell.
What looks like "two objects" in the passive is actually:
- A raised grammatical subject
- A single propositional complement (split across the raising)
4. The Answer
No, 'to allege' is not ditransitive. 🎯
It is best classified as monotransitive, taking a single clausal complement (a that-clause or an infinitival clause representing a proposition/claim).
The passive sentence "he is alleged to have seen him" is a raising-to-subject construction, not evidence of two separate objects. The apparent complexity comes from how English passivisation interacts with clausal complements — not from 'allege' having two distinct object arguments.
---
5. Memory Tip 💡
> "Ditransitive = two participants receiving something." > Ask yourself: "Can I give this verb an indirect object (a person as recipient) AND a direct object?" > With 'allege', the answer is no — you allege a claim, not a person a claim. ✅
⚠️ Common Mistakes to Avoid
- confusing grammatical objects with semantic participants
- misinterpreting infinitive complements as direct objects in passive constructions
- not recognizing that ditransitivity refers to active voice argument structure, not passive manifestations
