From ありがたく (arigataku), the adverbial form of Old Japanese and Classical Japanese adjective ありがたし (arigatashi, modern ありがたい, arigatai), from 有り (ari, the 連用形 (ren'yōkei, “continuative or stem form”) of verb 有る aru, “to exist, to be”) + 難し (katashi, “hard, difficult”, 難い katai in modern Japanese). The katashi changes to gatashi as an instance of rendaku (連濁).
Modern Japanese -i adjectives formerly ended in -ki for the attributive form. This medial /k/ dropped out during the Muromachi period, both for the attributive form (-ki becoming -i) and for the adverbial form (-ku becoming -u). However, the adverbial form reverted back to -ku thereafter for most words, with the -u ending persisting in certain everyday set expressions, such as arigatō, ohayō, or omedetō, and in hyper-formal speech.
Arigatashi is first attested in the oldest literature of the 8th century. Originally meant “difficult to exist, hard to be”, shifting to “rare, special”, and then to “welcome, thankful, nice to have” by some time in the 15th century. This sense is still in use: この天気はありがたいね。 ― Kono tenki wa arigatai ne. ― “This weather sure is welcome.”
