A — 1: Ὅλος (Strong'S #3650 — Adjective — holos — hol'-os )

"whole," is rendered "altogether" in  John 9:34 . It is sometimes subjoined to an adjective or a verb, as in this case, to show that the idea coveyed by the adjective or verb belongs to the whole person or thing referred to. So here, lit., "thou wast altogether (i.e., completely) born in sins." Cp.  Matthew 13:33 , RV;  Luke 11:36;  13:21;  John 13:10 , RV (rendered "every whit"). See All , and Every Whit

B — 1: Πάντως (Strong'S #3843 — Adverb — pantos — pan'-toce )

from pas, "all," is translated in various ways. The rendering "altogether" is found only in  1—Corinthians 5:10 (where the RV margin gives the alternative meaning, "not at all" (meaning the fornicators of this world) and   1—Corinthians 9:10 (marg., "doubtless"). The other renderings are, in   Luke 4:23 , "doubtless" (AV, "surely"); in  Acts 18:21 , "by all means," (AV, "only"); so in  1—Corinthians 9:22 , both RV and AV; in  Acts 21:22 , "certainly" (AV, "needs," which does not give an accurate meaning); in  Acts 28:4 , "no doubt;" in  Romans 3:9 , "in no wise" (lit., "not at all"), so in  1—Corinthians 16:12 . In  Acts 26:29 the AV has given a misleading rendering in the phrase "both almost and altogether;" there is no Greek word here which means "altogether;" the RV corrects to "whether with little or with much." See All.

B — 2: Ὅλως (Strong'S #3654 — Adverb — holos — hol'-oce )

denotes "altogether or actually, or assuredly." See Actually , and All, B No. 1.

King James Dictionary [2]

ALTOGETH'ER, adv. all and together. See Together.

Wholly entirely completely without exception.

Every man at his best estate is altogether vanity.  Psalms 39 .

Webster's Dictionary [3]

(1): (adv.) Without exception; wholly; completely.

(2): (adv.) All together; conjointly.

International Standard Bible Encyclopedia [4]

ôl - too - geth´ẽr  : Representing five Hebrew and three Greek originals, which variously signify (1) "together"; i.e. all, e.g. 'all men, high and low, weighed together in God's balance are lighter than vanity' (  Psalm 62:9 ); so also  Psalm 53:3;  Jeremiah 10:8 . (2) "all": so the Revised Version (British and American),  Isaiah 10:8 : "Are not my princes all of them kings?" (3) " with one accord have broken the yoke"; so the Revised Version (British and American),   Jeremiah 5:5 . (4) "completely," "entirely," "fully": "so as not to destroy him altogether" ( 2 Chronicles 12:12; compare  Genesis 18:21;  Exodus 11:1;  Psalm 39:5;  Jeremiah 30:11 the King James Version; compare the Revised Version (British and American)). (5) "wholly": "altogether born in sins,"   John 9:34 . (6) In  1 Corinthians 5:10 the Revised Version (British and American) rendered "at all";   1 Corinthians 9:10 "assuredly." (7) A passage of classic difficulty to translators is   Acts 26:29 , where "altogether" in the Revised Version (British and American) is rendered "with much," Greek en megálō ( en pollō̇ ). See Almost . Many of the instances where "altogether" occurs in the King James Version become "together" in the Revised Version (British and American). Used as an adjective in  Psalm 39:5 ("altogether vanity").
