Quoting Nickbbu (Thread starter): This might seem a bit weird, but I can assure you that this as serious as it can get. I am writing a study on LCC and I need to know exactly how should I write the title: low cost or low–cost ?
What is the right way of writing and why?
Most English style manuals would show "low-cost" (with a hyphen) as the preferred format. That is what is known as a compound adjective when used in the context of "low-cost carrier" or "low-cost manufacturer" etc, and it is usual to link the words in compound adjectives with a hyphen.
If "low" was an adjective modifying the noun "cost" or "costs" as in, "Ryanair operates with low costs", then a hyphen would be incorrect, but if you said, "Ryanair is a low-cost carrier" you would need the hyphen.
