"Coft" is the Scots past tense of "coff" (to buy), and its archaic quality gives it a folk and ballad flavour. It appears in verse and song as evidence of commercial transaction and practical life, and its brevity makes it metrically useful. In a literary culture that values the plain speech of ordinary life, "coft" belongs to the vocabulary of the market and the exchange, and its use in poetry insists on the economic dimensions of everyday existence that more elevated diction tends to ignore. It is a small word carrying a large material world.

Coft is a past tense form that has largely disappeared from everyday speech but survives in verse, ballad, and folk expression, where archaic forms are often preserved like insects in amber. Its appearance in a poem immediately signals either antiquity or deliberate archaism — a poet reaching back to an older register. The verb "to coff" (to buy) is itself rare, making "coft" doubly literary. Students studying historical Scots poetry should be comfortable with such archaic past tenses; the Scots verbal system preserves many forms that have been lost in Standard English. Compare with "wrocht" (worked) and "drave" (drove) as similarly archaic Scots past forms.
