Usage of the phrase 'cant able to'I can't able to do this work.
The phrase can't able to is an incorrect usage. I have heard many people using this phrase. There is no phrase as 'can't able' in English. It should be either will not be able or am not able depending on the person and the tense.
The correct version is the following:
'I will not be able to do this work' if it is future tense or 'I am not able to do this work' if it is present tense.
The same applies to the phrase 'can able'. This is a wrong usage. It should be 'will be able'.
For example the sentence 'Sita can able to dance' is wrong. The correct usage is 'Sita will be able to dance'.
