Etymology: from Proto-Indo-European *septḿ̥ (seven) [source]. Words from the same PIE root include seven, and words beginning with hepta-/sept(a/i)-, such as heptastyle (having 7 columns), septemplex (sevenfold), septasyllabic (having 7 syllables) and septilateral (having 7 sides) in English, and words related to seven in other Indo-European languages [source].

The Old Irish word sechtmain was borrowed from the Late Latin septimāna (week), from septimānus (related to the 7th element of a series), from the Latin septimus (7th) [source]. Words for week in Cornish and Breton probably came from the same roots.

A week in Welsh is wythnos (“8-night”), as weeks in Wales have an extra night. A weekend is penwythnos and a fortnight (2 weeks) is pythefnos (“15-night”).
