dipped

The verb 'dip' originates from the Old English 'dyppan', meaning "to immerse, baptize," which is a causative form of the verb 'duppan', meaning "to dive." This Old English root is of Germanic origin, related to Old Norse 'deypa' and German 'taufen' (to baptize). The core Proto-Germanic idea is one of a brief, plunging immersion, a sense which has remained remarkably stable. The modern word retains this literal sense of putting something briefly into a liquid, while also extending metaphorically to concepts like a downward slope or a temporary decline, as in "the road dipped."

The word 'dipped' is the inflected past tense and past participle form of the verb 'dip'. The base 'dip' is a simplex word of Old English origin. The suffix '-ed' is a productive inflectional suffix from Old English, used to form the past tense and past participle of regular verbs.
