Reciprocal verbs

2. Verbs that can have a reciprocal function. This category includes verbs that can also have a non-reciprocal function.

This category is further divided into the two following subcategories

2a. Verbs to which the reciprocal function causes a small or big change in meaning and (often) in valency.

Examples
not reciprocal	reciprocal function causes change in meaning	change in valency
einigen A	sich einigen auf A	yes	A --- auf A
aussprechen A	sich aussprechen	yes	A --- without an argument
treffen A	sich treffen mit D	yes	A --- mit D

The verbs of this group (like the ones that have only reciprocal use) can also be found in the singular number, combined with a prepositional object (mit + dative). Reciprocity can be, in most cases, emphasized with the word miteinander.

Examples
wir einigen uns (miteinander)	ihr einigt euch (miteinander)	sie einigen sich (miteinander)	PLURAL

ich einige mich mit jemandem			SINGULAR
