Etymology

The verb meaning to arm beforehand is formed from English fore- + arm (“to equip with weapons”).[2][3][4][5][6]

Earliest recorded meaning

To arm in advance for attack or resistance: Merriam-Webster dates it to 1584,[5] the OED to 1591, in Robert Greene's Second Part of Conny-catching,[2] and Barnhart to 1592.[4]

Semantic evolution

The OED records the verb both literally and figuratively from its first use.[2] Johnson (1755) defined it as providing for attack or resistance before the time of need.[7] Weekley noted that it was used only in the proverb forewarned is forearmed,[8] which the Shorter Oxford quotes.[6] Merriam-Webster gives the broader sense "to prepare".[5]

Timeline

  • 1584 – to arm in advance.[5] The OED's first quotation, of 1591, uses it literally and figuratively.[2]

Meanings

Verb

  1. To arm or prepare in advance for an attack, a danger or a difficulty: The guide's warnings forearmed us against the cold.[5][6][2]
