Comparative: staler
Superlative: stale
The word 'staler' comes from 'stale' (from Old English *stæl*, meaning stale or old) and the suffix '-er' (meaning one who). A staler is one who is stale or old, often referring to something that has lost freshness.
Think of something that is 'old' or 'not fresh' ('stale') and remember that a 'staler' is someone or something that embodies that lack of freshness.
