==Norwegian Bokmål==
{{wikipedia|1=en:Å,no:Å (bokstav),en:Aa (surname)}}

===Pronunciation===
* {{IPA|nb|/oː/}}
* {{rhymes|nb|oː|s=1}}
* {{homophones|nb|Å|å|aa}}
* {{hyphenation|nb|Aa}}

===Etymology 1===
From the older Danish–Norwegian digraph ⟨Aa⟩, used to represent the long vowel which developed from Old Norse {{m|non|á}} {{IPAchar|/ɑː/}}. The doubling of ⟨a⟩ originally indicated vowel length. In mainland Scandinavian, the vowel became rounded to {{IPAchar|/ɔː/}} and was later raised to {{IPAchar|/oː/}} in many varieties.

The Swedish letter ⟨Å⟩ developed graphically by writing the second ⟨a⟩ above the first, where it was eventually reduced to a ring. Norwegian retained ⟨Aa⟩ for several centuries under Danish orthographic influence. ⟨Å⟩ was permitted in Riksmål in 1907 and officially replaced ⟨Aa⟩ in ordinary Norwegian spelling through the spelling reform of 1917.

====Letter====
{{head|nb|letter|g=m|lower case|aa|definite singular|Aa-en|indefinite plural|Aa-er|definite plural|Aa-ene}}

# The uppercase form of {{m|nb|aa}}, formerly used in place of {{m|nb|Å}}, the twenty-ninth and final [[letter]] of the Norwegian Bokmål [[alphabet]].

=====Usage notes=====
* The spelling ⟨Aa⟩ was replaced by ⟨Å⟩ in ordinary Norwegian words and official place names in 1917.
* It remains in established personal names and certain other proper names, such as {{m|nb|Haakon}} and {{m|nb|Aase}}.
* When ⟨Aa⟩ represents ⟨Å⟩, it is alphabetized together with ⟨Å⟩ at the end of the Norwegian alphabet.
* The sequence may also be used as a substitute for ⟨Å⟩ when the latter character is unavailable, although modern Norwegian normally retains ⟨Å⟩.

===Etymology 2===
From a Norwegian habitational name written ''Aa'', the traditional spelling of {{m|nb|Å}}, ultimately from {{der|nb|non|á|t=small river}}.

====Proper noun====
{{head|nb|proper noun}}

# a Norwegian [[surname]]

=====Usage notes=====
* As a surname, ''Aa'' is an established spelling and is not automatically changed to ''Å''.
