Conjunctions

Aíþþáu and þáu
Aíþþáu and þáu have the same meaning, but whereas aíþþáu can mean "or" with a choice of multiple things, þáu rather means "or" is used for a choice between one thing or the other.

Þáu represents a possibility between two things without other options:

Matthew 11.3: þu is sa qimanda þáu anþarizuh beidáima? (Are you the one who is to come, or are we to look for someone else?)

Aíþþáu represents a possibility out of multiple things:

Colossians 2.16: ni manna nu izwis bidomjái in mata aíþþáu in draggka aíþþáu in dáilái dagis dulþáis aíþþáu fulliþe aíþþáu sabbatum. (Let no man therefore judge you in meat, or in drink, or in respect of a holiday, or of the new moon (lit.: full moon), or of the sabbath days.)

Ak
Ak has the meaning "but" and is almost always used after a negation.

Ni briggáis uns in fráistubnjái, ak láusei uns af þamma ubilin. (Lead us not into temptation, but deliver us from evil.) Ni is the negation of the first part, therefore ak is used in the second part.

Akei
Akei has the meaning "but" and is almost always used after a phrase which isn't a negation.

Matthew 5.22: aþþan ik qiþa izwis þatei ƕazuh modags broþr seinamma sware, skula wairþiþ stauai;

(But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council:)
