Prepositions after verbs

Start with, in, at, from or by?

Start commonly combines with several prepositions depending on whether you mean sequence, place, point, origin, or method.

Quick answer

Choosing the right preposition after start

Use start with for the first item or step, start in for location or field, start at for a point or level, start from for an origin, and start by for the first action in a process.

Let's start with introductions.
She started in finance before moving to law.
We should start by checking the data.

Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Using by for a noun topic

By introduces actions, not the first topic or item.

✕ Let's start by the budget discussion. ✓ Let's start with the budget discussion.

Confusing at and from

At gives a point or level; from gives an origin.

✕ Prices start from $10 in this sentence meaning minimum price. ✓ Prices start at $10.
