Lithiumians aren't particularly formal, but formalities are different. They are polite. Here is the definitive apology collection.

APOLOGIES

The prefix for apology is generally sok-. (excluding the formal leminot, leminote)

Here's some vocabulary.

Sok-ien/ A gesticulation made when apologising/ sohk-eeh-uhn

*Note: these are customised

Sok-rado/ To be inclined to say sorry (verb), a forced apology (noun)/ sohk-rah-doe

Sokrinoi/ Sorry/ Sohk-rihn-oy (More informal then leminot, leminote)

Now we have 'The' sorry's. To be more specific, Litish uses their renowned 24 The's to classify what they are apologising for. Here is an example, using the generalised 'The', ly. Please note that saying sorry like this always uses the plural form.

Sokrinoi'ly/ Sorry for anything classified under Lu or Ly/ Sohk-rihn-oy'lie

Lithiumians also like saying hi, and we've covered a few ways to say hi, Saluttions, Savle, Valon and Galto. However, we have some more.

MIND YOUR LANGUAGE!/ VENGUENOI!/ Vehn-gwen-oy
