Oa

Oa is a fictional planet that lies at the center of the DC Comics universe. Since its inception, Oa has been the planetary citadel of the Guardians of the Universe and the headquarters of the Green Lantern Corps. It first appeared in Green Lantern vol 2 #1, when the Guardians summoned Hal Jordan's "energy duplicate" so they could hear of his origin.

History

One of the oldest planets in the universe, Oa serves as the home and headquarters for a race of blue-skinned powerful humanoids who have dubbed themselves the Guardians of the Universe. The Guardians administer the Green Lantern Corps, a group of powerful universal police officers equipped by the Guardians with green-colored power rings along with green lanterns with which to charge the rings. According to the story "Heart of a Star" in the Sandman: Endless Nights graphic novel, Oa's star is called Sto-Oa (the Light of Oa) by the children of the planet's inhabitants. Its location has been firmly established by numerous references in Green Lantern comics over the years. It was formerly the center of the universe until the events of Infinite Crisis.

List of Latin-script digraphs

This is a list of digraphs used in various Latin alphabets. Capitalization involves only the first letter (ch – Ch) unless otherwise stated (ij – IJ).

Letters with diacritics are arranged in alphabetic order according to their base. That is, ⟨å⟩ is alphabetized with ⟨a⟩, not at the end of the alphabet as it would be in Norwegian, Swedish and Danish. Substantially modified letters such as ⟨ſ ⟩ (a variant of ⟨s⟩) and ⟨ɔ⟩ (based on ⟨o⟩) are placed at the end.

Apostrophe

⟨’b⟩ (capital ⟨’B⟩) is used in the Bari alphabet for /ɓ/.

⟨’d⟩ (capital ⟨’D⟩) is used in the Bari alphabet for /ɗ/.

⟨’y⟩ (capital ⟨’Y⟩) is used in the Bari alphabet for /ʔʲ/. It is also used for this sound in the Hausa language in Nigeria, but in Niger, Hausa ⟨’y⟩ is replaced with ⟨ƴ ⟩.

A

⟨a’⟩ is used in Taa orthography, where it represents the glottalized or creaky-voiced vowel /a̰/.

⟨aa⟩ is used in the orthographies of Dutch, Finnish and other languages with phonemic long vowels for /aː/. It was formerly used in Danish and Norwegian (and still is in some proper names) for the sound /ɔ/, now spelled ⟨å⟩.
