IPA: //ˈfrʌntɪst//
KK: /frʌntɪst/
The highest or most forward position or place; the most advanced or prominent part.
The frontest part of the line was reserved for the VIP guests.
This word originates from Old English, where 'front' (meaning the foremost part or position) is combined with the superlative suffix '-est' (indicating the highest degree). Therefore, 'frontest' refers to the most forward or foremost position.
Think of 'front' as the leading position and '-est' as indicating the highest degree, so 'frontest' means the very front or most forward.
