The adjective 'konstruktiv' (constructive) is closely related to the verb 'konstruieren' (to construct, build) and the noun 'die Konstruktion' (the construction / structure). The basic idea of 'building up' appears in all meanings.

In the meaning of 'helpful,' 'konstruktiv' (constructive) is very often combined with nouns that describe communication or ideas. Typical examples are 'konstruktive Kritik' (constructive criticism), 'ein konstruktiver Vorschlag' (a constructive suggestion), or 'ein konstruktives Gespräch' (a constructive conversation).

The meaning 'concerning the structure' belongs to technical language, especially in architecture and engineering. You can recognize it from technical topics such as building plans, structural analysis, or components.

positive
'positiv' and 'konstruktiv' can both describe something good or helpful, especially in conversations, criticism, or feedback. 'positiv' generally means good, friendly, or approving. 'konstruktiv' means that something helps and aims at a solution. Constructive criticism can also mention problems, but it remains helpful. So the words are not the same: positive feedback may simply offer praise, while constructive feedback often also shows what can be improved.
