*** chairó ***
chairó: to rejoice, be glad
Original Word: χαίρω
5463 xaírō (from the root xar-, “favorably disposed, leaning towards” and cognate with 5485 /xáris, “grace”) – properly, to delight in God’s grace (“rejoice”) – literally, to experience God’s grace (favor), be conscious (glad) for His grace.
5463 /xaírō (“glad for grace“) has a direct “etymological connection with xaris (grace)” (DNTT, 2, 356). S. Zodhiates (Dict, 1467) likewise comments that 5479 /xará (“joy”) and 5485 /xáris (“grace”) are cognate with 5463 /xaírō (“to rejoice”), i.e. all share the same root and therefore the same core (fundamental) meaning.
[The etymological link between 5463 /xaírō (“rejoice”), 5479 /xará (“joy”) and 5485 /xáris (“grace”) – i.e. that they are all cognates – is brought out by LS (p 1,976), Zod (Dict), CBL, Wigram’s Englishman’s Greek Concordance (Ed. Ralph Winters), Word Study Greek-English NT (Tyndale, Ed. Paul McReynolds); see also DNTT (2,356) and TDNT (9; 359,60).
TDNT likewise groups them as cognates, referring to 5479 (xará) as the noun-form (nomen actionis) and discussing them separately in terms of their distinctive connotations.]
