Superiorul ierarhic ajută echipa de proiect.

Because -ul is the definite article attached to a masculine singular noun in Romanian.

• superior = a superior / a boss / a superior officer
• superiorul = the superior

Romanian usually puts the definite article at the end of the noun, not as a separate word like English the.

So here:

• Superiorul ierarhic = the hierarchical superior / the line manager

If it were indefinite, you could say:

• Un superior ierarhic ajută o echipă de proiect.
  = A line manager helps a project team.

In Romanian, adjectives are usually placed after the noun.

So:

• superior ierarhic = hierarchical superior
• literally: superior hierarchical

This is the normal, neutral word order in Romanian.

Also, the adjective ierarhic agrees with superiorul in gender and number. Here both are masculine singular.

Romanian can sometimes put adjectives before the noun, but that often sounds more literary, emphatic, or stylistically marked. In everyday neutral language, superiorul ierarhic is the expected order.

Ajută is the 3rd person singular present tense form of the verb a ajuta, meaning to help.

So:

• a ajuta = to help
• ajută = helps / is helping

In this sentence, it matches the singular subject superiorul ierarhic.

A useful point: in Romanian, the present tense can often translate several English ways depending on context:

• helps
• is helping
• sometimes even does help

Also, ajută is one of those forms that can also be 3rd person plural, so context tells you whether it means he/she helps or they help.

Romanian often omits subject pronouns when they are not needed. This is called a pro-drop language.

So instead of saying:

• El ajută echipa de proiect. = He helps the project team.

Romanian very often just says:

• Ajută echipa de proiect.

In your sentence, the subject is already clearly expressed as Superiorul ierarhic, so adding el would be unnecessary unless you wanted emphasis or contrast.

For the same reason as superiorul: Romanian attaches the definite article to the noun.

• echipă = a team
• echipa = the team

Here, echipa is feminine singular definite.

So:

• echipa de proiect = the project team

If it were indefinite, you would have:

• o echipă de proiect = a project team

De proiect works like a noun modifier: it tells you what kind of team it is.

• echipă de proiect = project team
• literally: team of project

In Romanian, de + noun is very common for this kind of classification or type.

So echipa de proiect means:

• the project team
• the team working on a project

This is a very natural Romanian structure.

Compare:

• echipa de proiect = project team
• echipa proiectului = the project's team / the team of the project

The second version, echipa proiectului, sounds more specifically tied to one particular project and is more literally possessive. In many contexts, echipa de proiect is the more idiomatic way to say project team.

Because pe is not normally used here.

In Romanian, the marker pe is often used before direct objects that are people, personal names, pronouns, or sometimes highly specific animate beings.

Examples:

• Văd pe Maria. = I see Maria.
• Îl ajut pe profesor. = I help the teacher.

But in your sentence:

• echipa is a collective noun
• it is treated as a unit, not as an individual person

So Romanian normally says:

• ajută echipa de proiect

not:

• ajută pe echipa de proiect

• Superiorul ierarhic is the subject, so it is in the nominative
• echipa de proiect is the direct object, so it is in the accusative

However, an important thing for learners is that in Romanian, the nominative and accusative often look identical for many nouns.

So even though echipa is the direct object here, its form does not change.

That is very normal in Romanian.

The normal, neutral order here is:

• Subject + Verb + Object
• Superiorul ierarhic ajută echipa de proiect.

That is the most straightforward order.

Romanian does allow different word orders for emphasis, topic, or style. For example, if you want to emphasize the object, you might move it to the front, but Romanian often adds a clitic pronoun in that case:

• Echipa de proiect o ajută superiorul ierarhic.

That still means roughly:

• It is the project team that the line manager helps.

So the original sentence uses the most standard and learner-friendly order.

A rough pronunciation guide is:

Superiorul ierarhic ajută echipa de proiect
soo-peh-ree-OR-ul yeh-RAR-hik ah-ZHOO-tuh eh-KEE-pa deh pro-YEKT

A few helpful pronunciation notes:

• ă is a short neutral vowel, similar to the a in about
• j in ajută sounds like the s in measure
• ch in echipa sounds like k
• ie at the start of ierarhic sounds like ye

If you want to sound natural, the main stresses are approximately on:

• superiorul
• ierarhic
• ajută
• echipa
• proiect

If you want to say The line managers help the project team, you would say:

• Superiorii ierarhici ajută echipa de proiect.

Notice:

• superiorul → superiorii = the superiors / the managers
• ierarhic → ierarhici to agree in the plural
• ajută stays ajută in the 3rd person plural present

So Romanian gives you:

• singular: Superiorul ierarhic ajută echipa de proiect.
• plural: Superiorii ierarhici ajută echipa de proiect.
