I usually stress the importance of verb patterns to my students because I consider it to be one of the weakest spots for Spanish-speaking learners. The verb “to suggest” illustrates my point.
How should we use it?
1) SUGGEST + THAT SOMEONE + DO SOMETHING (subjunctive)
I suggest that she go to the supermarket with you
The subjunctive mode is the base form (infinitive form without “to”)
2) SUGGEST + GERUND (-ing form)
I suggest going to the cinema tonight.
3) SUGGEST + NOUN (SOMETHING)
Can you suggest some interesting places to visit?
IMPORTANT!! The gerund is a noun equivalent so that means either of the two grammatical categories can come after the verb suggest.
4) SUGGEST+ THAT SOMEONE + DID SOMETHING
I suggested that she went to the hospital.
5) SUGGEST + THAT SOMEONE + SHOULD DO SOMETHING
She suggested that they should call him immediately.
Some of these uses are more frequent among American English speakers and some among British English speakers.
