Monserrat is a variant spelling of the Catalan name Montserrat. It is likely the better spelling in Anglophone (English-speaking) countries given the correct pronunciation of the name. Monserrat / Montserrat is a Catalan name meaning ‘serrated mountain’. That may not be the most appealing meaning, but the exceptional beauty of the Montserrat mountain range near Barcelona, Spain might change your mind. Monserrat is, unsurprisingly, most common among the Spanish community. Montserrat is also one of the claimed homes of the Holy Grail according to Arthurian legends.
