Interlingua grammar
Interlingua keeps much of the spelling of Latin words, more near to the forms in English and French than to them in the other Romance languages. For example, it keeps q ([k]), y ([i]), ch ([k]), ph ([f]), rh ([r]), and th ([t]). It keeps also the common use of double consonants. More, it allows versions like ch for [ʃ], s between vowels like [z], c before e/i like [ts], g before e/i like [ʒ], qu before e/i like [k], etc.
