Life Cycle or Lifecycle

I'm working on a project entitled Β "The Life Cycle of a Soldier". I'm wondering if Life Cycle is still two words, should be one word (Lifecycle), or if it matters how I spell/typeset it? I'm inclined toward Life Cycle because it seems more formal, proper, correct. Also, as a graphic designer, I like that way it looks better on the page. Thoughts? Thanks!

Welcome to the forum, toptomato. Two words seems better imho. I haven't often seen lifecycle as one word ... sounds more like a brand name for an exercise device.
Google: "life cycle" gets 48.5 million hits, "lifecycle" gets 36.4 million. Many of the latter appear to be branded usage.
According to some online dictionaries, both are acceptable, though the one-word version is listed as an "alternate" spelling.


Ahh. That was an easy one. Thanks for concurring, and for taking the time to weigh in. Much appreciated! Done. Β

The software industry for some reason prefers the alternative spelling. However, the Merriam-Webster Collegiate Dictionary has an entry for "life cycle" when you search for "lifecycle" that seems to be suitable for the life cycles of software objects under definition 3.
