Definition

Not loyal or trustworthy; someone who cannot be relied upon or does not keep promises.

Example

He was considered faithless for abandoning his friends in their time of need.

Conversation

I can't believe he did that after everything we've been through.

I know, it feels so faithless of him to just walk away.

Exactly! It's like he didn't care about our friendship at all.

Right? It's hard to trust someone who's so faithless.

Synonyms & Antonyms

Root Explanation

Faithless → It is formed from "faith" (from Old French *feid*, meaning trust or belief) and "-less" (meaning without). The word "faithless" means without faith or trust.

Memory Tip

Think of being 'without' ('-less') 'trust' ('faith') — that's why faithless means lacking trust.
