I keep wondering about the origin of the word "gohirio" that has "hir" (long) in its middle - to postpone means you can wait a long time.
I presume it's a combination of "Gor" (sort of the equivalent of the "over" prefix) and as you're right "hir", so sort of "to overlengthen", though you could always check on GPC.
GPC is spectacularly unhelpful here, unless I'm using it wrong.
The etymology of gohirio is "the verb corresponding to the noun gohir" and gohir is "root/stem of the following verb" (which I presume means gohirio).
So, the verb is the verb for that noun and the noun is the noun for that verb.
Not very etymological!
First time in this refresher exercise for TheNews, I put 'to put off'. This was rejected as wrong. I still suggested that, in English, if I put off something I am postponing it!!! Could 'put off' be accepted?
