To bifurcate is to “fork twice,” that is, form “two” separate paths.
The English prefixes bi-, derived from Latin, and its Greek variant di- both mean “two.” The Latin prefix is far more prevalent in common words, such as bilingual, biceps, and biped; the more technical Greek di- appears in such words as diphthong and dilemma. You can remember bi- easily by thinking of bicycle, which has “two” wheels, and di- by remembering that the “dioxide” of carbon dioxide means that there are “two” oxygen atoms in the molecule CO2.

A dilemma is so difficult because there are “two” equally valid “suggestions” on the table!
The English prefixes bi-, derived from Latin, and its Greek counterpart di- both mean “two.” These “two” prefixes are used commonly, especially bi-.
Let’s begin with the frequently used English prefix bi-, which means “two.” A bicycle has “two” wheels. A biped, like homo sapiens, walks on only “two” feet, perfect for a bicycle! A biped also has a primary muscle known as a biceps, which has “two” heads that attach to bones in the upper arm. A biped also has binocular vision, which mean that she uses “two” eyes to see. And does a biped who is bilingual have “two” tongues? No … it just means that he speaks “two” languages fluently.
Calendars have many events that use the prefix bi-, which means “two.” For instance, the bicentennial of an institution or nation is a celebration commemorating “two”-hundred years of existence. Two words that are easily confused are biannual and biennial. A biannual event happens “two” times every year, whereas a biennial celebration happens once every “two” years. You can remember the difference because alphabetically the “a” of biannual comes before the “e” of biennial, and also happens first in time.
Now let’s go on to the Greek variant of bi-, or di-, which also means “two.” Carbon dioxide, or CO2, is a gas whose molecule has “two” oxygen atoms. If you are in a dilemma, you are unable to choose between “two” options, often both unappealing! A diphthong is a pair of or “two” vowels in a row in a word in the same syllable, such as “cloud” and “foil.” And a dipterous insect? It simply has “two” wings!
Today you got “two” for your money with both bi- and di-. Now you no longer need to be “twice” shy with words such as bipartite and diphyllous, for you know that each has something “to” do with “two!”
