1. To make a snowman was fun.
(What is the part of speech of 'fun'? A noun of an adjective?)
2. I make it a rule to get up at five in the morning.
3.I regard it natural to study math every day.
(Are the two sentences grammatical?)
4. The boat rocked so much that I got sick.
5. The boat rocked so much that I got seasick.
(Does 'sick' mean 'seasick' in the sentence? Are both the same? Thank you for your help. Have a great weekdays.)
1. fun = adjective
2 and 3 are fine.
4 and 5 are fine, too -- and yes, on a boat "sick" and "seasick" usually mean the same thing.
