Boy, does this word show up in a
lot of places.
All versions of meter, whether
poetic or a unit of distance, ultimately come from the same place, though interestingly,
it seems like the poetic meter is actually the first version to show up in
English sometime around
the fourteenth century, while the unit didn’t appear until the eighteenth century. The words
come from the
classical Latin
metrum, which means meter in the sense of
measure,
from the Greek
metron,
which is traced back to the
Proto
Indo European me-,
to measure.
So a meter is a measure. And though you might think that
mete is somehow
related, no, it’s not even a little.
What
is related is any
word that ends in -meter or -metry. The former means
an instrument for measuring—so a thermometer is an instrument for
measuring temperature, a barometer for measuring pressure—while the latter means
process of measuring.
Geometry, for example, is -metry plus Gaia of all things, making geometry literally the process of
measuring land. Similarly, symmetry, which showed up in the
mid sixteenth century, is from the Latin
symmetria, where the syn- means
together and the
rest is from metron. So a measure together. There’s also metronome, a musical
time keeper, which showed up in
1815.
It’s not exactly from meter, instead taken directly from the Greek metron, with
the addition of the PIE root
nem-, assign, allot, or take.
Also from meter is semester,
which didn’t show up until
1827 meaning a period of six months (it seemed a lot longer in school). It’s actually
German in origin, though that was taken from the classical Latin
semestris, from the phrase
cursus semestris,
a semester (or six month) course. That mestris is actually from
mensis,
month, which is from me-,
but we’ll get more into that next week.
Finally today, commensurate.
Which isn’t really used much these days, but means corresponding in magnitude.
It showed up in the
mid seventeenth century from the
Late Latin
commensuratus, which is a mix of the Latin
com,
together,
and
mensura,
a measure.
Commensurate is measuring together? Wait, isn’t that just symmetry?
