5112. CONCERNING ANGELIC SPEECH. It is to be observed, that, when spiritual angels speak, their words, which are intellectual ideas, have an affinity with the vowels e and i; and, when they name a there is still something of e or a therein; and, when they name u, then there is something of i or y. Hence it was given me to know, that, when their speech falls into human speech, it falls into such words as contain those vowels. But the words of the celestial angels have an affinity with a, o and u: for which reason [their speech] falls into such words as contain those vowels. When, therefore, man speaks with the latter, he is, then, diverted from words which contain e and i, to words in which a, o and u occur.
