õõnesid

õõnesid is the genitive plural form of the Estonian word "õõn," which translates to "hollow" or "cavity." In various contexts, "õõnesid" refers to multiple instances of emptiness, hollowness, or internal spaces.

In biology, "õõnesid" might describe the internal cavities within an organism, such as air sacs in birds or the spaces within certain plant tissues. It can also refer to the hollow structures of bones.

In geology, "õõnesid" can denote the empty spaces or voids found within rocks and soil. These can be formed by various geological processes like erosion, dissolution, or the presence of trapped gas bubbles.

In a more general sense, "õõnesid" can refer to any collection of hollow objects or spaces. For example, a box might contain several "õõnesid" if it's filled with empty containers. The specific meaning of "õõnesid" is therefore highly dependent on the surrounding context in which it is used. It consistently points to the existence of multiple internal or empty spaces.
