Spreizen

Spreizen is a German verb meaning to spread, widen or splay something so that its parts move apart. It is used across a range of contexts, including the human body, objects and mechanical assemblies, as well as in technical and artistic descriptions. In anatomy or daily language, one speaks of the arms, legs or fingers being spread apart. In engineering or carpentry, spreizen can describe forcing two parts apart, for example by using a wedge or spreader.

Etymology and usage notes: the verb originates from older Germanic roots and is related to similar forms in other Germanic languages, such as Dutch spreiden. The basic form is non-separable, but it can be used reflexively: sich spreizen, meaning to spread oneself, as in Die Finger spreizten sich. The past participle is gespreizt, used with auxiliary hat or sometimes sein in reflexive constructions.

Grammatical overview: present tense forms follow regular conjugation: ich spreize, du spreizst, er spreizt, wir spreizen, ihr spreizt, sie spreizen. The simple past is often spreizte, spreiztest, spreizte, spreizten, spreiztet, spreizten; the perfect uses gespreizt, e.g., Die Beine sind gespreizt.

Related terms and concepts: die Spreizung (the act or result of spreading, the width achieved), der Spreizwinkel (splay angle) in technical contexts, and der Spreizkeil or Spreizwerkzeug, tools used to spread components apart. In figurative language, spreizen can describe widening gaps, such as trends or distances.

In summary, spreizen denotes the act of widening or spreading components apart, with broad applicability from anatomy to engineering, and with a standard set of conjugations and related nouns.
