🎤Pronunciation
🌳Etymology
Origin
This phrasal verb combines three elements: 'sign' derives from Latin signum (mark, signature), originally meaning to mark or authenticate with one's name. The particle 'up' adds a sense of completion and enrollment, while 'by' indicates a temporal boundary or deadline. Together, 'sign up by' means to complete registration before a specified time.
Breakdown
sign (Latin signum: to mark or sign) + up (completion, enrollment) + by (before, by the time of). The combination forms a phrasal verb where each element contributes to the meaning: authenticate one's commitment (sign), finalize enrollment (up), and adhere to a deadline (by).
