bound morpheme separates itself from bondage

[alewka]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте:

Now it happens that many such derived forms have semantic equivalents which are single morphemes: 'unwell' = 'sick', for example, 'unhappy' = 'sad'. Furthermore, there are many equivalents which can take the form not of single words but of phrases where the bound morpheme separates itself from bondage and becomes free.

Заранее спасибо
