IPA: /ˈwɔːʃɪə/
KK: /ˈwɑːʃiər/
Having a watery or diluted quality; lacking substance or strength.
The soup was too washier than I expected, making it less satisfying.
Comparative: washier
Superlative: washiest
The word 'washier' is derived from 'wash' (from Old English 'wascan', meaning to cleanse or make clean) and the suffix '-ier' (meaning more). Therefore, 'washier' means more capable of washing or more inclined to wash.
Think of 'wash' as cleansing and '-ier' indicating a greater degree, so 'washier' means more cleansing.
