What is the difference between 「けれど」 and 「けれども」 and 「けど」?


「けれども」と「けど」と「けれど」はいったいどう違うんですか。「けれども」はテレビ番組でよく使われているが、「けれども」は「けれど」より丁寧ですか。

_**English translation:_** What exactly do 「けれども」 and 「けど」 and 「けれど」 mean?
They often use 「けれども」 on TV programs, but is 「けれども」 more polite than 「けれど」?




`けど` is short for `けれど`, and hence, is colloquial and less polite. `けれども` has
`も` 'even' added somewhat redundantly. I don't see clear differences between
`けれど` and `けれども`. The difference among the three may be parallel to the
difference among English `though`, `although`, and `even though`. So if a
native English speaker can tell the difference among them, it may be a clue
for telling the difference for the Japanese words.
