#vocabulary #bi_
Bilingual
using or knowing two languages
دوزبانه
bi (two, twice, double) + lingua (tongue, language) + al (suffix forming adjectives)
According to the studies, two mental advantages of being bilingual are: 1) better focus and planning of complex tasks; 2) higher ability to understand others' minds. While bilingualism is seen as a useful skill nowadays, its roots used to suggest that a speaker was lying, being hypocritical, or mixing up words from different languages.
Bilateral
affecting or undertaken by two parties
دوطرفه (قرینه)
bi (two, twice, double) + latus (side) + al (suffix forming adjectives)
The example sentence uses the adjective in a figurative way. A definition that connects more literally to the roots is "having identical parts on each side of an axis"--this can describe the symmetry between two sides of an object or organism, such as a plane's wings or a human's ears.
Bigamy
having two spouses at the same time
دو همسری
bi (two, twice, double) + gamos (marrying) + y (suffix forming abstract or collective nouns)
As the example sentence suggests, bigamy and polygamy are often seen as equally illegal. But a serial monogamist can also be considered a polygamist (since he marries often and creates many children and households in need of support), but he is not guilty of bigamy or polygyny, which is marriage to two or more women at the same time.
Binoculars
an optical instrument for simultaneous use by both eyes
دوربین شکاری
No need for telescopes or even binoculars, as the individual streaks of light can appear over large spans of the overhead sky.
bi (two, twice, double) + oculus (eye) + ar (suffix forming adjectives)
As the roots show, the word originated as an adjective to describe something with two eyes or that requires the use of two eyes. Before the addition of the "s" turned it into a noun, the optical instrument was called "binocular glass" or "binocle."
Biennial
occurring every second year
هر دوسال یکبار
bi (two, twice, double) + annus (year) + al (suffix forming adjectives)
Although the roots of "biennial" and "biannual" are the same, their meanings are not. Something that is biannual occurs twice a year, while something that's biennial occurs every two years. In botany, a biennial is a plant that lasts two seasons, unlike a perennial, which can last several seasons and often for more than two years.
