Forms

sēmipēs m (genitive sēmipedis); third declension[1][2]

Etymology

It is from Latin sēmi- (“half”) + pēs (“foot”).[1][3][4] The prefix goes back to Proto-Indo-European *sēm-i (“in one”), whose meaning shifted to “one of two” and then “half”;[5] pēs continues the Indo-European word for the foot, Proto-Indo-European *pōd-s.[5]

Earliest recorded meaning

Its earliest use is as a measure of length in Cato's De agricultura,[1][2][3] where a hole half a foot across is to be made in a wheel.[1]

Semantic evolution

As a linear measure of half a foot it belongs to the writers on agriculture and building: Varro, Vitruvius, Columella and Pliny the Elder use it for the breadth of boards, the depth of soil and the size of trenches.[1][2] In the Digest, Ulpian uses it of the half foot of ground that each of two neighbours contributes for a party wall.[1]

In prosody it is half a metrical foot: Gellius reports Varro's observation that in the hexameter the fifth half-foot always ends a word,[1][4] and Terentianus Maurus, Ausonius and Augustine in his De musica use it in the same way.[1][4] Prudentius uses it as an adjective of a man with one leg cut off, “half-footed”.[4][6][7]

Medieval British writers kept the measure and the metrical sense, the latter in Bede; a gloss also uses it of someone deformed in one foot.[8]
