I'm looking to create stylized t shirts with single common motivational words in the design, never multi-word phrases. Are single commonly used words such as 'intrepid', 'fearless', or 'strive' always in the clear? Below is a possible trademark issue I found for the word 'strive'. Thanks in advance!
