Connectors and Prepositions
Prepositions and linking words shape instructions and explanations in healthcare settings. This chapter reviews fixed collocations, condition words, and time prepositions that appear in patient guidance and workplace notes.
Fixed Collocations
Some phrases are fixed: 'take medication with meals'. Using the wrong preposition ('at meals') sounds unnatural, so these collocations are worth memorizing.
Condition and Contrast
'If' introduces a condition ('if your symptoms get worse'), while 'unless' means 'except if'. 'However' signals a contrast between two statements, such as normal results and a recommended follow-up.
Prepositions of Time
Clock times take 'at' ('at 8 a.m.'), days take 'on', and months or years take 'in'. Getting these right keeps schedules clear in written communication.
