===Clear Phrasing===

Because aspects are phrases, they come with all the ambiguities of language. If no one knows what your aspect means, it won’t get used enough. That isn’t to say you have to avoid poetic or fanciful expression; Just a Simple Farmboy isn’t quite as fetching as Child of Pastoral Bliss. If that’s the tone your game is going for, feel free to indulge your linguistic desires.

However, don’t do this at the expense of clarity. Avoid metaphors and implications when you can get away with just saying what you mean. That way, other people don’t have to stop and ask you during play if a certain aspect would apply, or get bogged down in discussions about what it means.

If you’re wondering if your aspect is unclear, ask the people at the table what they think it means.
