Algebra

Algebra is one of the broad areas of mathematics, together with number theory, geometry, and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating them; it is a unifying thread of almost all mathematics. It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.
 

Alliteration

In literature, alliteration is the conspicuous repetition of identical initial consonant sounds in successive or closely associated syllables within a group of words, even those spelled differently. As a method of linking words for effect, alliteration is also called head rhyme or initial rhyme. "Alliteration" is from the Latin word littera, meaning "letter of the alphabet"; it was first coined in a Latin dialogue by the Italian humanist Giovanni Pontano in the 15th century. 

Almond

The almond (Prunus amygdalus, syn. Prunus dulcis) is a tree native to Iran and surrounding countries but widely cultivated elsewhere. The almond is also the name of the edible and widely cultivated seed of this tree. The genus Prunus is classified with the peach in the subgenus Amygdalus, distinguished from the other subgenera by corrugations on the shell (endocarp) surrounding the seed. The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed, which is not a true nut inside. Shelling almonds refers to removing the shell to reveal the seed. Almonds are sold shelled or unshelled. Blanched almonds are shelled almonds that have been treated with hot water to soften the seedcoat, which is then removed to reveal the white embryo.
