Patronymics are formed from the father's (or sometimes mother's) first name:
- Male: Father's name + -son (son of)
- Female: Father's name + -dóttir (daughter of)
Examples:
- Jón Þorsson (Jón, son of Þor)
- Guðrún Jónsdóttir (Guðrún, daughter of Jón)
- Eiður Smári Guðjohnsen
Titles like Herra (Mr.), Frú (Mrs.), Dr., and Prof. are used. People are addressed by their first name, even formally. Surnames in the traditional sense are rare.

- ehf. (einkahlutafélag) – Private limited company
