More about prerogative
Prerogative 鈥渁 right limited to a specific person鈥� derives via Middle English from Latin 辫谤补别谤辞驳腻迟墨惫耻蝉 鈥渧oting first,鈥� a compound of the preposition prae 鈥渂efore鈥� and the verb 谤辞驳腻谤别 鈥渢o ask, propose.鈥� Prae is the source of the prefix pre-, which appears in three other words in this paragraph, while 谤辞驳腻谤别 gives rise to several question- and claim-related words, such as arrogant (originally meaning 鈥減resuming鈥�), interrogate, and surrogate (originally meaning 鈥渢o nominate as a substitute鈥�). Prerogative was first recorded in English in the late 1300s.

fortuitous
adjective
happening or produced by chance; accidental.
More about fortuitous
Fortuitous 鈥渉appening or produced by chance鈥� ultimately comes from the Latin noun fors (stem fort-) 鈥渃hance, luck.鈥� Though chance and luck are not quite one and the same, the overlap between the two is why fortuitous evolved a second, more common sense of 鈥渓ucky, fortunate.鈥� Also derived from fors is the noun 蹿辞谤迟奴苍补, which is the source of English fortune. The Roman goddess 贵辞谤迟奴苍补 was the goddess of luck as well as fate, and the Romans celebrated a festival in her honor, Fors 贵辞谤迟奴苍补, annually on June 24. Note that Latin fors is not related to the English words forte 鈥渁 person鈥檚 strength鈥� and fortify 鈥渢o strengthen against attack,鈥� which come instead from Latin fortis 鈥渟trong, brave鈥� (compare Spanish fuerte). Fortuitous was first recorded in English circa 1650.

He was a science fiction fan and he had converted his sister, Janet, to the true faith. He also told her about me and what a terrific lecturer and eccentric fellow I was. It roused her curiosity.

More about vanguard
Vanguard 鈥渢he forefront in any movement鈥� comes from the same source as the recent 51吃瓜 of the Day avant-garde: the Middle French terms avant 鈥渢o the front鈥� and garde 鈥済耻补谤诲颈补苍蝉丑颈辫.鈥� Avant, which means 鈥渂efore鈥� in modern French, comes from Latin ab ante, literally 鈥渇rom before.鈥� The preposition ab 鈥渇rom鈥� can be found in numerous English words that signify movement away from something, such as abduct (literally 鈥渢o lead away鈥�) and abstain (鈥渢o hold back鈥�), while ante 鈥渂efore鈥� appears in antechamber (鈥渂efore a room鈥�) and antediluvian (鈥渂efore a flood鈥�). Middle French garde is related both to English guard and ward, as the w sound in Germanic languages corresponds to g or gu in French; compare the recent 51吃瓜 of the Day guerdon. Vanguard was first recorded in English in the 1480s.
