There are meters and then there are meetorus
Someone asked me the other day which was the normal way to talk about meters in Japanese, as in “the plant is over two meters tall.” He wondered if it was meetaa or meetoru. I knew I’d heard (and possibly used) both before, but I wasn’t sure which was more common, so I guessed meetaa. Should have checked the dictionary first.
Consulting with the Daijirin, a large American Heritage-style dictionary (as opposed to the Koujien, which is sort of OED-ish), I found an interesting difference between the two. Both meetoru and meetaa have two senses. Meetoru’s first sense is the unit of measurement, and all related things: meetoru-hoo is the metric system ‘meter law/rule’. Meetaa’s first sense is “measurement device,” as in gasu meetaa ‘gas meter’ and paakingu meetaa ‘parking meter’. Did this bring me back to an earlier post? Yes it did. But this is rather minor, parallel to the pair sutoraiki ‘labor strike’ and sutoraiku ’strike (baseball/bowling)’.
(In fact, the “strike” pair is rather interesting because the final vowel is devoiced; if the two words had meanings similar enough that appeared in the same contexts, people might have some serious issues telling them apart.)
But remember that each of these words had two senses? Well, the second senses of each meetaa and meetoru says, basically, “see [the other word], sense 1.” Great, I thought. But it’s actually not that, uh, “simple,” because while meetaa indeed has both meanings, meetoru is always the unit of length: there is no gasu meetoru, at least according to one person I spoke with.
