Today I’m going to share two situations, one of which uses a hyphen, and one of which does not.
Rule of Thumb #1:
Use a hyphen before the word “type” when describing a type of item with a two-word adjective.
LED-type level gauges
Venturi-type flow meter
Rule of Thumb #2:
Do not use a hyphen when describing the identification number of an item.
Rule of Thumb #3:
Capitalize the noun that precedes the number in the above examples for Rule #2. Consider it a proper name for that row or version or phase or rig or model, and all proper names are capitalized.
Famous Quote of the Day:
“As a general rule, the most successful man in life is the man who has the best information.”
