Misleading Dictionary Entry of the Day
September 6th, 2017
#1.Entry: christiandom (x) - kekristenan (x)
This is not a valid English word. It just doesn't exist.
Most probably the lexicographer didn't re-check and just concluded from similar words such as (free - freedom), (martyr - martyrdom), etc.
The valid one is:
Christendom (noun) - Kekristenan dalam arti kolektif dilihat dari segi Sejarah Dunia (termasuk perkembangan dan lembaga-lembaganya).
Christianity (noun) - Sistem Kepercayaan Kristen dan arti keduanya sama dengan atas (Christendom).
Tips: always check, re-check, and investigate. In rare cases, even dictionaries make mistake.
