Let’s consider again the case of adjective modifiers (in classical grammar, this category of words are considered as degree adverbs). These include the following: peu, très, extrêmement, surtout, étonnamment, à peine, vraiment, assez, bien, trop, tellement, … = pocu, assai, estremamente, sopratuttu, in modu stunante, appena, propriu/propria/proprii/proprie, abbastanza, bellu/bella/belli/belle, troppu/troppa/troppi, troppe, tantu/tanta, tanti/tante, … = not very, very, extremely, especially, surprisingly, hardly, really, enough, all/very, too, so,… We have argued that this category of words are ‘adjective modifiers’, when they precede an adjective. But is such an assertion likely to be proven, or is there some form of evidence available? Grammar, like other disciplines, requires that assertions be justified, and if possible proven. The notion of proof in grammar, however, is uncommon. Let’s see if we can provide such proof or justification?

Consider the case of ‘tellement’ (so much), which we consider to be an adjective modifier when it precedes an adjective. Now, let us consider the following translations, where ‘tellement’ is used:

• in French: il est tellement beau, ils sont tellement petits, elles est tellement belle, elles sont tellement intelligentes
• in English: it is so beautiful, they are so small, they are so beautiful, they are so smart
• in Corsican: hè tantu bellu, sò tanti chjuchi, hè tanta bella, sò tante intelligente (an alternative translation hè: hè cusì bellu, sò cusì chjuchi, hè cusì bella, sò cusì intelligente)
• in Italian: è così bello, sono così piccoli, sono così belli, sono così intelligenti

It is patent here that ‘tellement’ preceding an adjective is translated in Corsican by:

• tantu, when the adjective is singular masculine
• tanti, when the adjective is plural masculine
• tanta, when the adjective is singular feminine
• tante, when the adjective is plural feminine

Thus ‘tellement’ (so much, tantu/tanti/tanta/tante), employed in this usage, i.e. preceding an adjective, accords with the adjective to which it refers. This sounds as a justification of its classification as an adjective modifier.
