By vs With
This guide explains the difference between using 'by' for methods of transport or communication and 'with' for physical tools or body parts.
A2Elementary
01 / Overview
Use by to describe a method, a system, or a way of traveling. Use with to describe the specific physical tool, object, or body part used to complete an action.
02 / By vs With
Note that when using by for transport, we do not use 'a' or 'the' (e.g., by bus, not by a bus). When using with, we usually need an article or a possessive adjective (e.g., with a knife, with my key).
| Preposition | Usage | Examples |
|---|---|---|
| by | Methods, transport, and communication | by car, by email, by credit card |
| with | Physical tools, instruments, and body parts | with a hammer, with a pen, with my hands |
