Describing something that has icicles hanging from it.
The trees were icicled after the freezing rain.
Icicled is derived from the word 'icicle' (from Middle English 'icicle', which comes from Old English 'isicel', meaning a piece of ice). The suffix '-ed' indicates a past participle form. Therefore, 'icicled' refers to something that has been formed into or covered with icicles.
Think of 'icicle' as a piece of ice, and when something is 'icicled', it means it has been covered with or formed into icicles.
