IPA: /ˈpiːkɪʃ/
KK: /ˈpikɪʃ/
Describing someone or something that looks thin or sharp, often due to illness, or relating to a peak or mountainous area.
After being sick for a week, she looked a bit peakish and tired.
The word 'peakish' is derived from 'peak' (from Middle English 'peke', meaning a pointed top or summit) and the suffix '-ish' (meaning having the quality of). Therefore, 'peakish' describes something that has the quality of a peak or is somewhat peak-like.
Think of a 'peak' as a pointed top, and when you add '-ish', it suggests something that resembles or has the quality of that peak.
