A vessel equipped with spars that are too large or too small is said to
be oversparred or undersparred.
Spar, v. i. [imp. & p. p. Sparred (?); p. pr. & vb. n. Sparring.] [Of
uncertain origin; cf. OF. esparer to kick, F. éparer, or Icel. sperra
to stretch out the legs, to struggle.] 1. To strike with the feet or
spurs, as cocks do.
2. To use the fists and arms scientifically in attack or defense; to
contend or combat with the fists, as for exercise or amusement; to box.
Made believe to spar at Paul with great science.
