as (much as) now; as it is now
Used in comparisons, typically with a negative predicate, to mean 'not as much as now' or 'not as ... as the present situation'. Often appears as 今ほど～ない.
There has never been a time as busy as now.
I've never been as concerned about him as I am now.
Refers to the very recent past; synonymous with たった今 or さっき. Less common than sense 1 and may be considered slightly old-fashioned or literary.
Regarding the matter you called about just now, I have confirmed it.
Standard kanji-kana spelling.
Rare kanji spelling using 程; 今ほど is far more common.
Compound of 今 (ima, 'now') and ほど (hodo, 'extent, degree'). The comparative sense developed from 'to the extent of now', while the temporal sense 'just now' is a later extension.
