I would like to know if I could say instead of ' I would prefer to go to the sea than to study' the following sentence : ' I would prefer to go to the sea than study' ; could the 'to' be omitted after 'than' ?
I am in two minds about this for more than one reason:
1) We don't usually say "go to the sea". Perhaps "go to the beach", "go to the seafront" (BrE), "go for a swim in the sea"?
2) If you omit "to" before study, leaving "I would prefer to go to the beach than study", there is a slight possibility that it can be read as "I would prefer to go to the beach than go to study".
For lack of ambiguity, I prefer "I would prefer to go to the beach than to study."
