This should be an easy puzzle.
Replace the x in the below with letters to make 6 valid 5-letters English words (no proper nouns or abbreviations) both vertically and horizontally.
This puzzle will be more fun if you only use a dictionary to validate your answers rather than use it to search for words that fit.

Green tick to the first valid answer that uses the least numbers of letters.
C x D x T
x x x
R x T x R
x x x
