Adjectives in Tamil do not have morphological forms for the `comparative' and `superlative' degrees like English and many other European languages (-er, -est, etc.). Adjectives can be compared, however, with the use of ÂÕ¹ vida (the infinitive of the verb ÂÕà vidu `leave, let'). The rule for this construction on the model of English ` A is big-ger than B' would be
` B ACC. ÂÕ¹ vida, A NOUN + È Éç¡Þ -aa irukku'.
The noun in this construction is adjectivalized and made comparative by the addition of the so-called ADVERBIAL suffix È aa (from LT È´/È² aaka/aay), which are both reduced to aa in ST. This, in combination with the copula, makes a `temporary-state' adjective. Note that È´ aaka is the INFINITIVE of ÈÞ aahu `become', and È² aay is the ADV (past participle) of the same.
Note that in the Tamil the order of the two items compared is B: A, while in English the order is A: B.
