What is a "suffix"?

A suffix is a type of affix that is added to the end of a base word or root to modify its meaning or grammatical function. Suffixes can change the part of speech, tense, or number of a word. For example, adding the suffix "-ing" to the verb "run" forms "running,", indicating an ongoing action. Similarly, adding the suffix "-ful" to the noun "beauty" creates the adjective "beautiful", which describes something that has beauty. Suffixes play an important role in word formation and help expand vocabulary in many languages.

What is a "grade"?

A grade is a mark given by a teacher to reflect how well a student is doing in a particular subject or course. It is typically represented as a letter (such as A, B, C) or a number, with higher marks indicating better performance. Grades are used to assess a student's understanding of the material, skills, and overall progress throughout the term. They are often used in determining academic achievement, influencing future opportunities such as higher education or job prospects.
