Each issue we will include a few common errors that crop up time and time again. If you have a personal favourite you think we should add to this section, please email me and I will try to include it in a future issue of HOC.
Dangerous Dyads
- Anesthesia, Anesthetic
Terms are not interchangeable. Anesthetics are substances or drugs used primarily to induce anesthesia , which is the loss of the sensation of pain.
- Cohort, Colleague
One may be a member of a cohort , but other members of the group are colleagues , not cohorts. A cohort is a specific, discrete group or subgroup, not an individual.
- Dose, Dosage
These words are not synonymous or interchangeable. A dose is the quantity administered at one time or the total quantity administered. The dosage is the regulation or frequency of doses. Dose could be thought of as a one-shot deal, and dosage as the timing or periodity.
- Nauseous, Nauseated
To be nauseous is to cause nausea, to be loathsome or abhorrent. To be nauseated is to become ill.
- Precribed, Proscribed
To prescribe is to direct, lay down rules, or give or write a prescription for someone. To proscribe is to forbid, prohibit, or condemn.
- Use, Usage
The simple word use is underused. Usage means traditional or customary practice; it pertains to mores as well as to words. It should not be used as a variant of use.
- Viral, Virile
Virus means slime, stench, or poison. [Viral refers to virus.] Virile is synonymous with masculine and means having the characteristics of an adult man. Pharmaceutical companies would not promote antivirile medications!
