Old English was a very complex language, at least in comparison with modern English. Nouns had three genders (male, female and neuter) and could be inflected for up to five cases. There were seven classes of “strong” verbs and three of “weak” verbs, and their endings changed for number, tense, mood and person. Adjectives could have up to eleven forms. Even definite articles had three genders and five case forms as a singular and four as a plural. Word order was much freer than today, the sense being carried by the inflections (and only later by the use of propositions). Although it looked quite different from modern English on paper, once the pronunciation and spelling rules are understood, many of its words become quite familiar to modern ears.
