Common Mistakes to Avoid
This chapter targets errors that even confident learners make: the gerund after 'look forward to', 'since' versus 'for', singular 'neither', and 'than' versus 'then'.
Since vs For; Look Forward To
Use 'since' with a starting point and 'for' with a duration. 'Look forward to' is always followed by a gerund because 'to' is a preposition.
Neither and Comparisons
'Neither' takes a singular verb in standard usage. In comparisons, use 'than' (not the time word 'then') and form short comparatives with '-er'.
