The term 'PRECEDER/ENDER OF 'A'' can be solved by the 4-letter word MANO. This word is derived from Spanish and Portuguese, meaning 'HAND'. It is often used to refer to a style of Latin American music and dance, which is characterized by a strong rhythmic pattern played on a guitar or other stringed instrument. In this context, it can be seen as the precursor or ender of the letter 'A', as it is the first and last letter of the word.
