Grammar?

CalifJimYes. You haven't got much choice. I suppose you could say to start cleaning the rooms if you wanted, but what you have is fine.

CalifJimB. Is it okay to use "on Wednesday"as follows?He likes to start to clean the rooms on Wednesday.Yes. That's fine.

CalifJimThis one is also fine. 'on Wednesday' is also going to be interpreted as a time-point adverbial, by the way, because of the word 'start', which indicates a point in time. 'on Wednesday' ~ 'at some specific time on Wednesday'.

Thank you so much, CalifJim.

CalifJimIt wasn't that disturbing. I only cried for 10 minutes.

Joseph AA. Is it okay to use two infinitives in a row in one sentence as follows?
He likes to start to clean the rooms on Wednesdays.

Yes. You haven't got much choice. I suppose you could say to start cleaning the rooms if you wanted, but what you have is fine.

Joseph AB. Is it okay to use "on Wednesday"as follows?
He likes to start to clean the rooms on Wednesday.

Yes. That's fine.

Joseph AC. Or should it be time-point adverbial as follows?
He likes to start to clean the rooms at 10.30am.

This one is also fine. 'on Wednesday' is also going to be interpreted as a time-point adverbial, by the way, because of the word 'start', which indicates a point in time. 'on Wednesday' ~ 'at some specific time — the starting time — on Wednesday'.

Joseph AI'm sorry for my disturbing question.

It wasn't that disturbing. I only cried for 10 minutes.

Sorry, I have a related question.

1. He likes eating ice cream on Friday.

2. He likes to eat ice cream on Friday.

Does #1 sound unnatural to you? If so, is it only because of "on Friday"?

If so, Is that a general rule? I mean, we shouldn't use a gerund whenever we want to specify a time.

Moonrise1. He likes eating ice cream on Friday.

It implies that he doesn't like to eat ice cream on Monday, Tuesday, Wednesday, Thursday, Saturday and Sunday. This is very strange, isn't it? It would raise some eyebrows!

This fixes it a bit.

He likes eating ice cream, especially on Friday.

Moonrise2. He likes to eat ice cream on Friday.

It is something he looks forward to or enjoys on Fridays.

Put the adverb first. Use the plural. Otherwise, it sounds quite odd.

On Fridays, he likes to eat ice cream.

Moonrise1. He likes eating ice cream on Friday. ...
Does #1 sound unnatural to you? If so, is it only because of "on Friday"?

I'd say "on Fridays". Otherwise, it sounds fine to me, even though it makes me wonder about the circumstances that led to that situation. Why just Fridays? Maybe ice cream is only available in his area on Fridays. I know I just tried to buy some ice cream last Monday, and they were all out of it.

CalifJimI'd say "on Fridays".

Excuse me CalifJim, why was "Wednesday" okay in my OP? Even I didn't pluralize it.

I like to clean the rooms on Wednesday.

You said, "It's okay". But in Moonrise's sentence, we should pluralize "Friday".

Regards,

Joseph
