[unscaled]

Japanese actually has a confusing array of conditional constructions

  VERB (conjugated) + nara (or the ridiculously formal "naraba")
  VERB (conjugated) + some noun, such as baai (case)
  VERB (plain form) + to
  VERB (izenkei form) + ba
  VERB (past form) + ra

And there are complex forms such as:

  VERB (plain form) + to shitara
  VERB (plain form) + to sureba

And you can add moshi or moshimo in the beginning to increase the level of supposition.

Each has a slightly different use and meaning of course, but it's still confusing enough for me even now.
