The word "millary" is spelled with two L's, contrary to what one might expect. The reason for this is that the word comes from the Latin "mīliārius", which is pronounced "mi-li-AHR-ee-oos" with the stress on the second syllable. In English, the stress is placed on the first syllable, and the second I is pronounced with a schwa sound instead of a full vowel. This gives the word its unique spelling and pronunciation, and its meaning of relating to or resembling small seeds or grains.
The term "millary" has its roots in Latin. It comes from the Latin word "milliarius", which means "consisting of a thousand". It is derived from "mille", meaning "thousand". In English, "millary" is typically used as a combining form to indicate a factor of a thousand or a unit of measurement equivalent to one thousand. For example, "millimeter" refers to one thousandth of a meter.
