There are (at least) two ancient Greek words for "
word".
The ancient Greek word "ῥῆμα" ≈ "spoken word" as in a saying. In grammar it referred to a "verb" and is the source of the English word "rhetoric".
The ancient Greek word "λόγος" ≈ "rational explanation" but is translated as "word" in John 1:1, in the beginning was the "word". It is the source of the English word "logic".
In general, one word means a spoken word and one means a written word but this distinction is not always followed.
There are many verses in the
LXX (Septuagint) and
GNT (Greek New Testament) that use both words. Such verses may help understand both the similarities and the differences between the two words.
