By vs With
A2 ElementaryThis guide explains the difference between using 'by' for methods of transport or communication and 'with' for physical tools or body parts.
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.
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 |
