What does augmented mean?
'Augmented' describes something that has been made larger, stronger, or better through the addition of something else — whether funds added to a budget, forces added to an army, or capabilities added to human perception. It functions chiefly as the past tense and past participle of the verb 'augment' and as an adjective meaning 'enhanced' or 'increased'. Beyond its general sense of amplification, the word holds two prominent specialized meanings. In music theory, an augmented interval or chord is one that has been expanded by a half step beyond its usual size. In computing, 'augmented reality' refers to technology that superimposes digital images or data onto the user's view of the real world, enriching rather than replacing it. The word derives from the Latin 'augere', meaning 'to increase', a root shared with 'author'. Its connotations are neutral to positive: what is augmented is typically improved, not merely inflated.
Past tense and past participle of 'augment': to have made something greater by adding to it.
"The garrison was augmented by fresh troops before the siege began."
Most often used in passive constructions in formal writing.
Increased or enhanced in size, amount, or quality; also, in music, raised by a semitone; in technology, combined with digital content.
"An augmented workforce was needed for the holiday season."
The same Latin root that gives us 'augmented' gave us 'author' — an author was originally someone who makes things grow.

Etymology of augmented
'Augmented' comes from the Latin verb 'augere', meaning 'to increase', via the frequentative form 'augmentare', which passed into Old French as 'augmenter' before entering English in the late Middle Ages. The same Indo-European root underlies 'author' — originally one who causes growth — and connects to words like 'auction' and 'August'. Its musical sense developed from Renaissance theory, and its technological sense emerged in the late twentieth century with 'augmented reality', coined around 1990 by Boeing researcher Tom Caudell.

How augmented is actually used
'Augmented' is somewhat formal in everyday use but is now ubiquitous in technical contexts thanks to 'augmented reality'. In music theory it is a precise technical term with no evaluative meaning. The verb 'augment' takes stress on the second syllable (au-GMENT), which is preserved in the participle.
