Hreyfir

Hreyfir is the third-person singular present indicative form of the Icelandic verb hreyfa, meaning to move or to cause something to move. It is used when the subject is he, she, or it and is a common form in everyday Icelandic.

Origin and usage: The verb hreyfa is inherited from Old Norse and is used transitively, taking a direct object for the thing moved (for example, hann hreyfir bílinn, he moves the car). The reflexive form hreyfa sig means to move oneself. Hreyfir appears in sentences describing physical movement as well as metaphorical movement in broader contexts.

Grammar notes: hreyfa is the infinitive; hreyfir marks the present tense for the third-person singular. Icelandic verbs in this area follow a predictable pattern, with other present-tense forms used for different persons and numbers. In practice, hreyfir will typically be encountered in descriptive or narrative contexts, where a subject performs the action of moving something.

Related forms and derivatives: Related terms include hreyfa (the infinitive) and hreyfing (movement). The verb participates in common collocations such as moving a body part, an object, or, in idiomatic use, moving plans or processes.

Examples: Hann hreyfir hendina. Hún hreyfir bílinn. Hún hreyfir sig. These illustrate a direct object and reflexive use, illustrating both literal and idiomatic movement in contemporary Icelandic.

In summary, hreyfir is a key present-tense form of hreyfa, used for he/she/it to describe moving or causing movement, rooted in Old Norse and widely employed in modern Icelandic.
