Which reading of その他 is more common?


What is the actual common reading of その他? Is it そのほか or そのた? Are there
differences in social or grammatical context, or a nuance in the actual
meaning?

  * スーパー大辞林 doesn’t list その他 as a word. There is an example with その― for ほか, but not for た.
  * ウィズダム和英辞典 lists そのほか only as a link to そのた.
  * Yomikatawa simply says そのほか.
  * Weblio contains some entries beginning both with そのほか and そのた, some of them with the other as a variant and others without it. By itself it is listed as そのほか with そのた as a variant.

I wasn’t able to abstract any rule, but I’m still not sure whether they’re
freely interchangeable.
