was light. Ancient Greek had a totally different rule, but it likewise restricted the accent to the last three syllables and could be seen as mora-based. In Japanese, the pitch accent of the standard Tokyo dialect places the accent on the antepenultimate mora by default in loanwords. This has been argued to be the result of an underlying preference in Japanese for antepenultimate mora accentuation, with the exception of a certain phonological configuration (four-mora words ending in a sequence of light syllables and a non-epenthetic vowel) which loanwords are particularly unlikely to satisfy.
