Liquids

Strictly speaking the liquid consonants are λ and ρ. These are sounds which are made with the tongue partly obstructing the flow of air, with the air thus flowing around the sides of it. However for the purposes of Koine Greek, verb stems ending with λ, ρ, and nasals μ and ν are considered liquids. This is an important category because liquid stems form the future and aorist in a slightly different way.

Which letters are liquids can be remembered with the mnemonics: LeMoNaR or LaMiNaR
