2556: Zetacism and Lambdacism Dec 12, 2021

Rhotacism, named from the Greek letter Ρ, ρ (rho), is the process of sounds shifting and becoming like /r/. Other terms with names taken from this pattern like zetacism or lambdacism do not always have the same implication. For instance, zetacism occurs when /z/, the most common sound to be effected to /r/ via rhotacism, remains not rhotacized even though it would be expected to. Lambdacism can refer, rather counterproductively, to either a difficulty pronouncing the /l/ sound, or an overproduction of the /l/ sound especially in place of /r/. This happens in some varieties of Carribean Spanish, such as saying 'Puelto Rico'.
