Weak inflection

In grammar, the term weak (originally coined in German: schwach) is used in opposition to the term strong (stark) to designate a conjugation or declension when a language has two parallel systems. The only constant feature in all the grammatical usages of the word "weak" is that it forms a polarity with "strong"; there is not necessarily any objective "weakness" about the forms so designated.

Germanic grammar

Other languages

In other languages the strong-weak polarity is used to express distinctions that may or may not be analogous. In Hebrew, most verbs have three consonants known as radicals. These can be strong (able to carry a full syllable) or weak (likely to collapse under the weight of a prefix or suffix). Verbs with a weak radical are termed weak verbs, and form partially regular exceptions to the normal conjugation rule. The consonants he, waw, and nun are among those likely to make a verb weak.

Regularity

The terms "weak" and "strong" rarely overlap with the idea of "regular" and "irregular"; some descriptions of English verbs contrast "weak" with "irregular", but this is misleading. It is true that most English or German weak verbs are regular, whereas Germanic strong verbs, despite the regularity of the system, are normally taught as irregular verbs; but there are also irregular weak verbs in English and German, and in Hebrew the weak verbs are the most irregular ones. In the case of the German noun, the strong noun is the norm, while the weak noun is usually taught as the anomalous form, though in fact it has its own regularity. In the German adjective, both systems are equally regular and equally common.
