Question

Teacher says , ''do it today itself"

Answer 1

If the intention of ‘itself’ in the sentence is an intensifier, it is a poor choice. Something like ‘without fail’ works better. Since its placement in the sentence is unusual, it can make the sentence difficult to interpret since the noun ‘list’ could syntactically be an antecedent but logically it is not so more confusion ensues.

Answer 2

Teacher says , ''do it today itself"

Teacher tells her to do it that day itself.
