Common mistakes

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

Using “evidence for” when meaning direct proof

Evidence of usually fits better when naming the condition or fact proved.

✕ There was evidence for water damage. ✓ There was evidence of water damage.

Treating “evidence with” as a fixed pattern

With normally adds extra information rather than forming a standard combination with evidence.

✕ The report contained evidence with corruption. ✓ The report contained evidence of corruption.

Quick practice

Choose the expression that matches the intended meaning.

1. There is strong evidence ___ fraud.
2. The scientist presented evidence ___ the theory.
