Unique
Definition 1 of 5
Pro Tip 1/3
Absolute Singularity
Use 'unique' to stress something's sole existence in its category, not just rarity. The language has a unique writing system, not found elsewhere.
Pro Tip 2/3
Avoid 'Very Unique'
'Unique' implies 'one of a kind,' so intensifiers like 'very' are unnecessary. Her voice is unique; no need to say 'very unique.'
Pro Tip 3/3
No Comparisons
Don't compare by saying something is 'more unique' than another. His solution is unique, not 'more unique' than hers.
