Formell vs. förmlich vs. formal
While the German words formell, förmlich, and formal all translate to "formal" in English, they serve specific purposes. Formell relates to etiquette and official rules, förmlich describes stiff behavior or acts as an intensifier, and formal focuses on structure and technical validity.
Formell
B1This word describes adherence to external rules, customs, etiquette, social standing, or official procedures. It is the direct opposite of informell (informal) and is used when talking about dress codes, official education, or professional interactions.
Für diesen Anlass ist formelle Kleidung vorgeschrieben.
(Formal attire is mandatory for this occasion.)

(She enjoyed a very formal education at a university.)

(The minister is paying a formal visit to the neighboring country.)
Wir sollten das Problem auf formellem Weg lösen.
(We should solve the problem through the official channel.)
Förmlich
C1This word has two distinct uses. First, it describes behavior that is strictly ceremonious, stiff, or overly polite to the point of being distant. Second, it is widely used as an adverb/intensifier meaning literally, positively, or veritably to emphasize a dramatic action.
Obwohl sie Kollegen sind, gehen sie sehr förmlich miteinander um.
(Although they are colleagues, they treat each other very ceremoniously.)

(The atmosphere in the room was stiff and formal.)

(The house was literally taken apart by the storm.)

(He was positively foaming with rage on the phone.)
Formal
B2This adjective relates to the outer form, structure, logic, or technical correctness of something, as opposed to its content (inhaltlich). It is frequently used in legal, bureaucratic, aesthetic, or academic contexts where technical validity is crucial.
Der Vertrag ist aufgrund eines formalen Fehlers ungültig.
(The contract is invalid due to a technical error.)
Das ist nur eine formale Angelegenheit und hat nichts mit dem Inhalt zu tun.
(That is just a procedural matter and has nothing to do with the content.)

(We must check the formal criteria for the application.)

(The story is good regarding content, but has structural weaknesses.)
Summary
Use formell when discussing social etiquette, dress codes, official procedures, or qualifications. Use förmlich when describing stiff behavior or when emphasizing that something literally happened. Use formal when referring to structure, technicalities, shape, or legal validity independent of the content.
