Word Origin & Etymology

Formed in the late 16th century as an agent noun from the verb 'blot' (of Middle English origin, likely related to Old Norse 'blettr' meaning 'stain' or 'spot'). The sense of a daily record book arose because such ledgers originally had sheets of blotting paper interleaved between the pages to dry fresh ink.
