Syntax
Old English, like its
contemporary European languages, was a highly inflected language.
Meaning was determined by case endings: that is, the relationship
among words in a sentence was determined not by the order of the
words in the sentence, but by the special endings of the words that
determined which nouns were the subject, direct object, or indirect
object; whether the nouns and verbs were singular or plural; whether
the nouns were masculine, feminine, or neuter; and whether certain
relationships of agency or action operated among nouns and verbs (we
now use prepositions for this).
