Frequently Asked Questions
No, it is extremely rare and is considered a highly technical or literary term. Most native speakers will never use it and may not know its meaning.
The most common mistake is confusing it with the much more common word 'inspire'. They are unrelated in meaning and etymology.
Yes, though less commonly. It can be used intransitively (e.g., 'The liquid inspissated over several days') as well as transitively (e.g., 'He inspissated the liquid').
'Inspissated' is the past participle of the verb 'inspissate', and it functions as an adjective meaning 'thickened' or 'made dense'. This adjectival form (e.g., 'inspissated pus') is more frequently encountered than the verb form.
