—Pronunciation note In pronouncing nuclear, the second and third syllables are most commonly said as
/-kli
ər/[-klee-er], a sequence of sounds that directly reflects the spelled sequence ‑cle‧ar. In recent years, a somewhat controversial pronunciation has come to public attention, with these two final syllables said as
/-kyə
lər/[-kyuh-ler]. Since
/-kli
ər/[-klee-er], the common pronunciation of ‑cle‧ar, might also be represented, broadly, as
/-klə
yər/[-kluh-yer], the
/-kyə
lər/[-kyuh-ler]pronunciation can be seen as coming from a process of metathesis, in which the
/l/[l] and the
/y/[y] change places. The resulting pronunciation is reinforced by analogy with such words as
molecular, particular, and
muscular, and although it occurs with some frequency among highly educated speakers, including scientists, professors, and government officials, it is disapproved of by many.
