Anonymous:Which sentence is correct?
I have not ran the air conditioning this year.
I have not run the air conditioning this year.
the present perfect requires the infinitive, not the past tense
Yesterday I sang.
I haven't sung that particular song in hears. Past participal - sung - not the infinitive.
Grammar GeekI'm not good at the names of things, but don't you mean it requires the past participal, rather than the inifinite?Stupid error on my side, guess I was ready to take my nap: of course it's the past participle which is required in the present perfect.
Funny site: can't edit my erroneous posting any more.
Thanks for pointing that up.
Aside from verbs which do not change at all (cut, quit, ...), the only verbs which have the same form for infinitive and past participle are run (run, ran, run) and come (come, came, come) and their compounds (rerun, become, ...).
