(of a voice) loud and harsh
Every day at this hour, the vegetable vendor comes down this street with his strident cry.
stridere (utter an inarticulate sound, grate, screech) (Latin)
Think of "stree" (wife) + "dant" (tooth). A girl's mouth is always loud and harsh - craving for supremacy or attention. s+TRIDENT= the OBEROI 'n TRIDENT hotel waz occupied by terrorists' and they were loud and harsh on the hostages Very close to 'Student', just ri=u. Anyway primary students are always loud and harsh.
