since Latin prefixes are used i would assume Vigitagenarian perhaps spelling isn't correct & for 30 trigintagenarian
i saw this on wikipedia this is more likely to be correct:
Ages can also be divided by decade:
Term Age (years, inclusive)
Denarian 10 to 19
Vicenarian 20 to 29
Tricenarian 30 to 39
Quadragenarian 40 to 49
Quinquagenarian 50 to 59
Sexagenarian 60 to 69
Septuagenarian 70 to 79
Octogenarian 80 to 89
Nonagenarian 90 to 99
Centenarian 100 to 109
Supercentenarian 110 and older

It's certainly possible for a 12 year old to thinkthey're in love with a 20 year old.But realistically, 12 is too young for any kind of real romantic love, whether it's with another 12 year old, a 20 year old, or an 80 year old.
