Alphabetizing, Spelling, Data Comparison & Filing (Sub-Pro level)

Alphabetizing Rules

Rule 1: Letter by Letter

Compare words letter by letter from left to right.

Example: APPLE comes before APPLICATION (compare A-P-P-L...)

Rule 2: Nothing Before Something

Shorter words come before longer words when the beginning is the same.

Example: AN comes before AND

Rule 3: Names - Last Name First

File by: Last name, First name, Middle name

Example: CRUZ, Juan M. comes before SANTOS, Ana B.

Rule 4: Prefixes

Treat prefixes (De, Dela, Del, San, etc.) as part of the name.

Example: DE LA CRUZ files under D, not L

Practice: Arrange alphabetically

Santos, Maria | San Juan, Pedro | Sanchez, Ana | Santa Maria, Jose

Answer: San Juan, Sanchez, Santa Maria, Santos
