This character is a Other Letter and is mainly used in the Runic script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+16AA forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
Ansuz is the conventional name given to the a-rune of the Elder Futhark, ᚨ.
The name is based on Proto-Germanic *ansuz, denoting a deity belonging to the principal pantheon in Germanic paganism.
The shape of the rune is likely from Neo-Etruscan a (), like Latin A ultimately from Phoenician aleph.
