Affection (linguistics)
Affection (also known as vowel affection, infection or vowel mutation), in the linguistics of the Celtic languages, is the change in the quality of a vowel under the influence of the vowel of the following final syllable. It is a type of anticipatory (or regressive) assimilation at a distance. The vowel that triggers the change was later normally lost. Some grammatical suffixes cause i-affection. In Welsh, "word" and "device suffix" yield "dictionary", with in becoming . The two main types of affection are a-affection and i-affection. There is also u-affection, which is more usually referred to as u-infection. I-affection is an example of i-mutation and may be compared to the Germanic umlaut, and a-affection is similar to Germanic a-mutation. More rarely, the term "affection", like "umlaut", may be applied to other languages and is then a synonym for i-mutation generally.
