Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
Both “foci” and “focuses” are accepted plurals of “focus.” Do not assume the Latin-derived “foci” makes “focuses” incorrect; dictionaries record both forms.
Both “formulas” and “formulae” are accepted plurals of “formula.” Do not present “formulae” as the only correct plural or treat “formulas” as an error: both are dictionary-recorded forms.
