especially
Used to single something out from a group or to emphasize it in particular. It means something like 'above all' or 'particularly'.
Ich mag viele Sportarten, insbesondere Fußball.
I like many sports, especially soccer.
The word is made up of the preposition 'in' and the adjective 'besondere' (special). It literally means that something is being considered or emphasized 'in particular'.

All the colleagues were friendly, especially those from my department.
'Insbesondere' (especially) can stand at the beginning of a sentence and then introduces inversion, where the verb follows in second position. But it can also stand directly before the word or phrase it emphasizes.
Insbesondere die neuen Regeln sind schwer zu verstehen.
Especially the new rules are hard to understand.
'Insbesondere' (especially) is often used in written language, in formal contexts, and in specialist texts. It often sounds somewhat more formal and precise.
Die Studie untersucht Risikofaktoren, insbesondere den Einfluss von Stress.
The study examines risk factors, especially the influence of stress.
all
'all' is meant here as part of the fixed expression 'vor allem' (above all / especially). 'vor allem' and 'insbesondere' both single something out from a group. 'vor allem' sounds very natural in everyday language and is often used in conversations. 'insbesondere' points in the same direction, but sounds somewhat more formal and fits well in written texts, explanations, or official notices. Both say: this point is especially important or is meant in particular.
