Підгин широкий.

In Ukrainian, the verb to be is usually omitted in the present tense in simple sentences like this.

So:

• Підгин широкий = The hem is wide

But in other tenses, бути appears:

• Підгин був широкий = The hem was wide
• Підгин буде широкий = The hem will be wide

So the sentence is complete even without a separate word for is.

It is a full sentence.

It has:

• Підгин = the subject
• широкий = the description/predicate adjective

So it means The hem is wide, not just wide hem.

If you wanted only the noun phrase wide hem, you would normally say:

• широкий підгин

That is a phrase, not a full statement.

Because it agrees with підгин.

Підгин is:

• masculine
• singular
• nominative

So the adjective must also be:

• masculine
• singular
• nominative

That gives широкий.

For comparison:

• широкий підгин = masculine singular
• широка спідниця = feminine singular
• широке поле = neuter singular
• широкі штани = plural

Not exactly.

• Широкий підгин usually means a wide hem or wide hem as a noun phrase.
• Підгин широкий means The hem is wide as a sentence.

So the difference is important:

• adjective + noun = a thing described
• noun + adjective here = a statement about that thing

In normal Ukrainian, that sounds unnatural for this meaning.

For simple present-tense descriptions, Ukrainian usually does not use є:

• natural: Підгин широкий
• unnatural in most everyday contexts: Підгин є широкий

The word є is more often used for:

• existence: Тут є магазин = There is a shop here
• emphasis or certain formal styles

So for The hem is wide, just say Підгин широкий.

Usually it refers to the folded-under edge of fabric, especially in sewing or clothing contexts. In English, hem is often the best translation.

Depending on context, it can also suggest:

• a turned-up edge
• a folded edge
• the hemmed part of a garment

So hem is a very natural translation, but the exact nuance can depend on what is being discussed.

Because Ukrainian has no articles like English a/an and the.

So Підгин широкий could be understood as:

• The hem is wide
• A hem is wide

In real life, context tells you which one is meant. In most translation exercises, The hem is wide is the most natural English rendering.

Yes, Ukrainian word order is flexible, but the meaning and emphasis can shift.

• Підгин широкий = neutral statement: The hem is wide
• Широкий підгин = usually a wide hem (a phrase, not a full sentence)
• Широкий підгин could sound sentence-like only in special spoken contexts with strong intonation, but learners should not rely on that

So for a clear basic sentence, Підгин широкий is the safest pattern.

You simply add не before the adjective:

• Підгин не широкий = The hem is not wide

You could also replace the adjective with an opposite one:

• Підгин вузький = The hem is narrow

Both are correct, but they are slightly different:

• не широкий = not wide
• вузький = narrow
