Dictionaries — a mini table
P40.lists-and-tables.02 · Audience: guest, language-pro, it-ml · Prerequisites: Lists — a row of things
Tally the words in a paragraph on paper and you naturally draw a two-column table: each word once, a running count beside it. This module gives that table its code name — the dictionary — the shape the whole discipline builds toward, one idea at a time.
ⓘ Concept: Each key maps to a value
{"the": 4, "cat": 2}. Your paper tally is a dictionary: the word is the key, its count is the value.Why it matters — A tally, a translation memory, a term-to-definition list — all of these are key-to-value tables. The dictionary is the shape a language professional reaches for most.
