When you use pairs like 'both . . . and', 'not only . . . but also', or 'neither
. . . nor', make sure that each word in the pair is in the right place. The two
words should introduce symmetrical structures, e.g. 'both at home and at work',
not 'both at home and work'.
Strictly speaking, you should say either 'He looked neither to right nor to
left' or 'He looked to neither right nor left', but not 'He looked neither to
right nor left'. Similarly, a sentence like 'She is not only a talented singer
but writes her own songs' is badly formed. You could rewrite it as either 'She
is not only a talented singer but also a composer' or 'She not only sings but
also writes her own songs'.
