I was watching http://youtu.be/FiqsDshUSDA?t=6m40s. At the 6th minute, he reads 傾げたく as かしげたく.
Goo's dictionary gives a preference for the かしげる reading (insofar as かたげる lists かしげる as a meaning).
Another site claims that the かしげる reading is 一般 in contemporary Japanese.
My question is this:
Is it acceptable to pronounce it かたげる?
How is the difference characterized between using the two pronunciations (if it is acceptable to say it かたげる)? [nuance, region, antiquated sound]
