English grammar has minimal inflection compared with most other Indo-European languages. For example, Modern English, unlike Modern German or Dutch and the Romance languages, lacks grammatical gender and adjectival agreement. Case marking has almost disappeared from the language and mainly survives in pronouns. The patterning of strong (e.g.speak/spoke/spoken) versus weak verbs (e.g. love/loved or kick/kicked) inherited from its Germanic origins has declined in importance in modern English, and the remnants of inflection (such as plural marking) have become more regular.

At the same time, the language has become more analytic, and has developed features such as modal verbs and word order as resources for conveying meaning. Auxiliary verbs mark constructions such as questions, negative polarity, the passive voice and progressive aspect.
