亻 rén

person (radical form)

semantic

言 yán

speech; word

Right 言 - speech radical with mouth at the bottom and tongue/sound waves above. The compound is a perfect ideograph: a person standing by their words is trustworthy. From 'a person whose word is good' came every modern sense - trust, belief, a letter (a written word), a signal (a transmitted word). Pure semantic compound, no phonetic role.
