I just recently came across "assist someone do" searching Google for examples to my previous question, and would like to check with you whether it is an acceptable option to "assist someone to do (or "in/with" doing)", or a snapshot of language in transition -- analogous with "help someone do" -- that I caught here.

Please consider the following examples for this:

NAFDAC is to assist you do your business right.source

Our company will assist you do your assignments...source

    Normally assist takes an infinitive with to in the B configuration; omitting it is not correct. This may be an analogy with help, which does allow optional to-deletion in the B configuration. This came up in a recent question. Commented Mar 4, 2014 at 20:33

    It's common for advertising slogans to be a bit ungrammatical, as these examples are. It makes them more memorable.

1 Answer 1


The correct form, as you point out, is 'to assist someone to do (or "in/with" doing)"'.

Quote 1 is from an ESL source, and could be interpreted as 'here to insist you do' or 'here to help you [to] do'.

Quote 2 is ungrammatical. It should be 'assist you in/with doing'.

I couldn't locate quote 3, but comment is as per quote 2.
