Eurolengo is a constructed language invented by Leslie Jones in 1972.: 156 It was constructed to be a common European language and "a practical tool for business and tourism.": 154 
The vocabulary consists of words borrowed from English and Spanish: 1 and made to conform to a consistent phonetic and orthographic system. Critics find a Spanglish flavor to the language, and that "reading is only straightforward if the requisite languages (in this case English and Spanish) are already familiar.": 157
Auxiliary languages in general, and regional ones such as Eurolengo in particular, have had little support from the international community; Eurolengo has never had any speakers.
According to its author, there are only three pages of grammar rules.
The Eurolengo alphabet is almost the same as the English alphabet, except there is no C (its phonemes being taken over by either S or K),: 156 but the Ch digraph is treated as a letter.
a=ah, b= bay, ch = chay, d=day, e = eh, f=eff, g=gay, h=ash, i = ee, j = jay, k = kay, l = ell, m = em, n = en, o = oh, p = pay, q=kw, r=air, s = ess, t=tay, u = oo, v = vee, w=wee, x = eks, y = eye, z = zed
According to its author all verbs are regular.
Nouns in Eurolengo have no gender, but a suffix can be added to derive specifically feminine words from their masculine counterparts, such as in the case of making kusin into kusina to indicate a male cousin or a female cousin.
