The term YOUTHFUL TIME can be broken down into two crossword solutions: SAL (3 letters) and TEENS (5 letters). SAL is an abbreviation for the Latin phrase 'sine anno limite' which translates to 'without a time limit'. This phrase is often used to describe something that is timeless or ageless. TEENS is a shortened form of the word 'TEENAGERS', which refers to people between the ages of 13 and 19. Together, these two words describe a period of life that is full of energy, enthusiasm, and optimism - a youthful time.
