noun, noun, used as a suffix, counter

The kanji 度 originally means 'degree' or 'measure', and its use as a counter for times is a natural extension. The reading たび is native Japanese, while the on'yomi ど is used in compounds like 一度 (いちど). The variant たんび is a colloquial contraction, possibly influenced by dialectal speech.
