Preposition after adjective

Literate in, about, by, to or on?

Literate is most commonly followed by in when referring to knowledge or skill in a subject. Other prepositions are usually uncommon or belong to different sentence structures.

Quick answer

Use literate in for areas of knowledge or skill

The standard pattern is literate in plus a field or system: literate in coding, literate in finance. Literate about is uncommon and usually replaced by knowledgeable about. Literate by, literate to, and literate on are generally nonstandard after the adjective.

She is literate in digital media.
Students should become literate in basic finance.
He is knowledgeable about climate policy.

Choose the pattern by meaning

These forms are not interchangeable. Choose the construction by meaning, not by which preposition appears most often.

1
literate in + subject

Show ability or knowledge in a field

Use in with subjects, technologies, or systems.

2
financially literate

Use literate without a following preposition

Many common expressions use literate directly before an adjective or noun modifier.

3
knowledgeable about + topic

Use a natural alternative for topics

About is more natural with knowledgeable than with literate.
