FAQs
How can I rephrase "either from which" for clarity?
Consider using alternatives like "from either of which", "of which either", or rephrasing the sentence to use "any" or "one" depending on the intended meaning. For example, instead of "a situation either precluded involvement or from which clients readily disengaged", try "a situation that either precluded involvement or "led clients to readily disengage"".
When is it appropriate to use "either from which"?
It's appropriate when you are explicitly presenting two options and indicating a source or origin for both. If there are more than two options, consider using phrases like "any of which" or restructuring the sentence to avoid ambiguity.
What's the difference between "either from which" and "either of which"?
"Either from which" emphasizes the origin or source related to two options, while "either of which" focuses on selecting one of two options. The subtle difference lies in whether the focus is on the source or the selection.
Is "either from which" considered formal or informal language?
It tends to appear more frequently in formal and technical writing, as it explicitly defines a choice within a specific context. However, it's crucial to ensure clarity; simpler phrasing might be preferable in informal contexts.
