Who is the Oldest Member of TWICE? Unpacking the "Unnie Line"
For fans of the globally popular K-Pop girl group TWICE, knowing the members inside and out is part of the fun. From their synchronized choreography to their infectious personalities, each member brings something unique to the table. A common question among both new and long-time fans is about the group's age order, and specifically, "Who is oldest in TWICE?" The answer to that is Nayeon.
Im Nayeon: The Eldest and "Fake Maknae"
Im Nayeon, universally known as Nayeon, holds the title of the oldest member in TWICE. Born on September 22, 1995, she is the eldest of the group, leading the "unnie line" – a Korean term for older sisters or older female friends. Despite being the oldest, Nayeon is often affectionately nicknamed the "fake maknae" due to her youthful appearance, bright energy, and playful demeanor, which can sometimes rival that of the actual youngest members.
Nayeon's journey to becoming a global K-Pop star began when she was scouted by JYP Entertainment at a young age. She then underwent years of rigorous training before debuting with TWICE in October 2015. Her captivating vocals, sharp dance moves, and charming stage presence have made her a standout performer and a beloved figure among ONCE (the official fandom name for TWICE).
The TWICE "Unnie Line" vs. "Maknae Line"
TWICE is often divided into two age-based sub-units: the "unnie line" and the "maknae line." The "unnie line" consists of the older members, while the "maknae line" comprises the youngest members. This distinction is not just about age but also about the dynamics within the group, with the older members often taking on more of a nurturing or guiding role.
The members of the "unnie line," in order from oldest to youngest, are:
- Nayeon (born September 22, 1995)
- Jeongyeon (born November 1, 1996)
- Momo (born November 9, 1996)
- Sana (born December 29, 1996)
And the members of the "maknae line" are:
- Jihyo (born February 1, 1997)
- Mina (born September 24, 1997)
- Dahyun (born May 28, 1998)
- Chaeyoung (born April 23, 1999)
- Tzuyu (born June 14, 1999)
It's worth noting that Jihyo, while technically part of the "maknae line," has been a trainee for an exceptionally long time (over 10 years) before TWICE's debut, leading her to be perceived by many as a mature and responsible leader, almost like an older sister figure herself.
Nayeon's Role and Influence
As the oldest member, Nayeon often sets the tone for the group with her positive energy and strong work ethic. She has taken on significant roles within TWICE, including being a powerful vocalist and a center for many of their iconic performances. Her bright personality and genuine interactions with fans have contributed greatly to TWICE's widespread appeal. She also successfully debuted as a solo artist in 2022 with her mini-album "IM NAYEON," showcasing her individual talents.
Understanding the age order within TWICE adds another layer to appreciating the group's dynamic. It highlights the camaraderie and the unique blend of maturity and youthful exuberance that makes TWICE such a beloved and enduring act in the K-Pop industry.
