Pro Tip

Common Collocations

Pair 'resistant' with 'to' and a noun (e.g., resistant to antibiotics, resistant to change). Avoid using 'resistant' alone without specifying what it resists.

Gold Rule

Avoid Redundancy

Do not use 'resistant' with words like 'immune' or 'unaffected' in the same sentence, as they convey similar meanings (e.g., avoid 'She is resistant and immune to the virus').

Word Origin

From Latin *resistent-* (stem of *resistens*), present participle of *resistere* 'to resist', from *re-* 'back' + *sistere* 'to stand'.

Usage Notes

The word 'resistant' is often followed by 'to' when describing what something resists (e.g., resistant to heat). It can also be used in compound adjectives (e.g., fire-resistant, rust-resistant).
