261. Some verbs of the Third Conjugation in -uó, -uere, are formed from noun-stems
in u- and have lost a consonant i: -
- statuó (for statu-yó), -ere, to set up, from status, position.
- metuó, -ere, to
fear, from metus, fear.
- acuó, -ere, to
sharpen, from acus, needle.
- arguó, -ere, to
clear up, from inherited stem argu-, bright (cf. o ).
NOTE: Many verbs in u are
inherited, being formed from roots in u: as, fluo,
fluere, flow; so-lvó (for sé-luó, cf. ), solvere, dissolve. Some roots have a
parasitic u: as, loquor, locútus, speak.
