Sissehingatava

Sissehingatava is an Estonian adjective form meaning “inhalable” or “capable of being inhaled.” The base form is sissehingatav, formed from the verb sissehingama (“to inhale”) plus the adjectival suffix -atav. The form sissehingatava is the genitive or partitive singular of this adjective, used when it modifies a noun in those cases, for example in phrases like “sissehingatava tolmu osakaal” (the proportion of inhalable dust).

In usage, sissehingatav describes substances or particles that can be breathed into the respiratory tract. The term is common in pharmacology, toxicology, and occupational health, where it helps distinguish materials that can be inhaled from those that are less likely to enter the lungs. Typical collocations include “sissehingatav aerosool” (inhalable aerosol) and “sissehingatav tolm” (inhalable dust). In regulatory and scientific texts, the distinction between inhalable fractions and other particle sizes is important for exposure assessments and risk evaluation. The concept aligns with international terms such as “inhalable” and is often discussed alongside the respirable fraction, which refers to finer particles that reach the deep lungs.

Etymology and morphology: the word is built from sissehingama and the suffix -atav, with sissehingatava functioning as a declined form of the adjective. While the base adjective is more commonly used in neutral descriptions, sissehingatava appears in contexts requiring genitive or partitive usage.
