The word is made up of 'Buch' (book) and 'Stab' (staff, stick). Historically, written characters (runes) were carved into rods made of beechwood, hence the name 'Buchstabe' (letter).
Der Name beginnt mit dem Buchstaben M.

'Der Buchstabe' (letter) belongs to the N-declension. This means it takes the ending '-n' in all cases except the nominative singular.
Ich kann den letzten Buchstaben des Wortes nicht lesen.

The expression 'nach dem Buchstaben' (to the letter) is used almost only in connection with rules or laws. It expresses a very strict, literal interpretation.

meaning / sense
'der Sinn' and 'der Buchstabe' form a contrast in the expression 'nach dem Buchstaben des Gesetzes' (to the letter of the law). Here, 'Sinn' means the intention or purpose of a rule. 'Buchstabe' does not simply mean an individual letter like A or B, but the very exact wording of a rule. Learners may confuse this because 'Buchstabe' normally means a written character. But with rules and laws, the question is often: Is someone only following the words, or do they also understand the meaning behind them?

Der Beamte entschied streng nach dem Buchstaben des Gesetzes.
The official decided strictly according to the letter of the law.
Beim Lernen hilft es, den Sinn einer Regel zu verstehen, nicht nur die Wörter auswendig zu lernen.
When learning, it helps to understand the purpose of a rule, not just memorize the words.
