Reforms suggested by the International Committee for the Development of East Timorese Languages (IACDETL) in 1996 included the replacement of the digraphs "nh" and "lh" (borrowed from Portuguese, where they stand for the phonemes and ) by "n̄" and "l̄" , respectively (as in certain Basque orthographies), to avoid confusion with the consonant clusters and , which also occur in Tetum. Thus, "senhor" "sir" became "sen̄ór", and "trabalhador" "worker" became "trabal̄adór". Later, as adopted by IACDETL and approved by the INL in 2002, "n̄" and "l̄" were replaced by "ñ" and "ll" (as in Spanish). Thus, "sen̄ór" "sir" became "señór", and "trabal̄adór" "worker" became "traballadór". Some linguists favoured using "ny" (as in Catalan and Filipino) and "ly" for these sounds, but the latter spellings were rejected for being similar to the Indonesian system, and most speakers actually pronounce "ñ" and "ll" as and , respectively, with a semivowel which forms a diphthong with the preceding vowel (but reduced to , after ), not as the palatal consonants of Portuguese and Spanish. Thus, "señór", "traballadór" are pronounced , , and "liña", "kartilla" are pronounced , . As a result, some writers use "in" and "il" instead, for example "Juinu" and "Juilu" for June and July ("Junho" and "Julho" in Portuguese).
