charismatic adj.

1875, "special spiritual gift or power divinely conferred, talent from God" (as on the early Christians in "Acts," etc.), Latinized form of Greek kharisma "favor, divine gift," from kharizesthai "to show favor to," from kharis "grace, beauty, kindness" (Charis was the name of one of the three attendants of Aphrodite), which is related to khairein "to rejoice at" (from PIE root *gher- (2) "to like, want").

In the form charism (plural charismata) it is attested in the "special spiritual gift from god" sense from 1640s. Middle English, meanwhile, had karisme "spiritual gift, divine grace" (c. 1500).

These gifts were of two classes, the gift of healing and gift of teaching, the latter again being of two kinds, the gift of prophecy and the gift of tongues. Such gifts have been claimed in later ages by certain teachers and sects in the church, as the Montanists and the Irvingites, and in recent times by some of those who practise the so-called faith-cure. [Century Dictionary, 1897]

The meaning "gift of leadership, power of authority" is from c. 1930, from German, used in this sense by Max Weber (1864-1920) in "Wirtschaft u. Gesellschaft" (1922). The more mundane sense of "personal charm" recorded by 1959.

Middle English -ik, -ick, word-forming element making adjectives, "having to do with, having the nature of, being, made of, caused by, similar to," from French -ique and directly from Latin -icus or from cognate Greek -ikos "in the manner of; pertaining to." From PIE adjective suffix *-(i)ko, which also yielded Slavic -isku, adjectival suffix indicating origin, the source of the -sky (Russian -skii) in many surnames. In chemistry, indicating a higher valence than names in -ous (first in benzoic, 1791).

In Middle English and after often spelled -ick, -ike, -ique. Variant forms in -ick (critick, ethick) were common in early Modern English and survived in English dictionaries into early 19c. This spelling was supported by Johnson but opposed by Webster, who prevailed.
