What does blotchy mean?
Blotchy is an adjective describing something covered with irregular spots, patches, or discolourations that break up an otherwise even surface. It is most often applied to skin — a blotchy complexion or rash — but is equally at home describing badly applied paint, uneven printing, stained fabric, or mottled stone. Because the marks it describes are typically unwelcome, the word carries a mildly negative connotation: nobody praises a surface for being blotchy. It derives from 'blotch', an older noun for an unsightly spot, and it has a close cousin in 'splotchy', formed from 'splotch'. Writers use it wherever visual unevenness needs a quick, vivid label, making it a handy descriptive term in both medical contexts (rashes, bruising) and everyday ones (decorating, photography, ageing materials).

Etymology of blotchy
Blotchy is formed from the noun 'blotch', meaning an irregular spot or blemish, combined with the adjective suffix '-y'. 'Blotch' itself appeared in English by the early seventeenth century and is probably a blend of 'blot' (a stain or spot) and 'botch' (a clumsy patch or blemish), though its exact origins are uncertain. The derivative adjective followed soon afterwards, and the related form 'splotchy' arose from 'splotch', a variant of the same word family.
