✦Grammar Breakdown

Preciso (verbo precisar)
‘Preciso’ is the first‑person singular of the verb ‘precisar’, which means ‘to need’. It is always followed by the preposition ‘de’ when the object is a noun.
da = de + a
The preposition ‘de’ contracts with the feminine singular article ‘a’ to form ‘da’, meaning ‘of the’. Here it links ‘preciso’ with ‘ajuda’.
de + um
When the noun that follows is masculine singular and indefinite, ‘de’ stays separate: ‘de um profissional’ = ‘of a professional’.
com isso
‘Com’ means ‘with’ and ‘isso’ refers to something previously mentioned or understood from context.

The verb ‘precisar’ must be followed by the preposition ‘de’ before a noun.
Preciso da ajuda de um profissional com isso.
Avoid placing ‘com isso’ after ‘profissional’; it should modify the whole clause, not the noun.
Preciso da ajuda de um profissional para isso.
‘Para isso’ is also correct, but learners often confuse ‘com’ and ‘para’; both are acceptable, yet ‘com’ stresses the tool/means, while ‘para’ stresses the purpose.

Cultural Tip
In Brazilian Portuguese, using ‘preciso de ajuda’ is very common and sounds natural. Adding ‘profissional’ or ‘especialista’ makes the request more formal and signals that you value expertise. When speaking to someone you don’t know well, keep the tone polite and, if appropriate, follow up with a thank‑you (e.g., ‘Obrigado pela ajuda’).
