Roots alter according to whether the first vowel is tense or lax.[1] Also, if the second vowel is open (i.e., /aː/ or /a/), then the first vowel is more open and centralised (e.g., [mɛːka] 'goat', as opposed to [mku] 'nail').[citation needed] Telugu words also have vowels in inflectional suffixes that are harmonised with the vowels of the preceding syllable.[2]
