There are a bunch of Greek loanwords in English that orthographically include the vowel sequence 'ae'. Examples include:
The 'ae' vowel here is pronounced [i] in English, but at least according to those Wikipedia pages, it was pronounced [a͡ɪ] in the Greek these words were borrowed from.
How did this convention come about?
- Were these words borrowed long enough ago that some vowel shift has happened in English since then?
- Is the [a͡ɪ] pronunciation only true for ancient Greek, and the [i] reflects their pronunciation in modern Greek?
- Something else?
