prepositional errors

By

• We say by car, by bus, by plane etc. but if there is a determiner (e.g. a/an, the, some, his), we say in or on:

• We use with, not by, to refer to the object or instrument that we use to do something!

determiner

a word placed before a noun to define, specify, or quantify it, providing essential context regarding ownership, number, or definiteness (any, a, this, one, his)

at

• We use at, not in, for points of time or place: What are you doing at the weekend?

phrasel verbs using in

Fold in, Set in (Take root; begin and continue e g winter has set in)
