Does somebody know for what the [がしら]{gashira} ending stands in radicals like:
- eight (はちがしら{hachigashira})
- winter (ふゆがしら{fuyugashira}), or
- short thread (いとがしら{itogashira})?
Is it part of あし{ashi} (bottom radical position) or ashi variant (center radical position / top and bottom radical position)? I understand the other endings (kanmuri, gamae-kamae, hen-ben, nyō, tare, etc.).
I know some of them don't have those endings and could be phonetic (sound) parts of kanji and not semantic (meaning).
