Hebrew adjectives must agree with the noun they describe in gender, number, and definiteness. Unlike English, the adjective comes after the noun: יֶלֶד גָּדוֹל (yeled gadol) = literally 'boy big'.

Adjective Comes After the Noun

In Hebrew the adjective always follows the noun: סֵפֶר טוֹב (SE-fer tov) = a good book (literally: book good).

Definiteness Agreement

When the noun is definite (has הַ), the adjective must also get הַ:
• יֶלֶד טוֹב = a good boy
• הַיֶּלֶד הַטּוֹב = the good boy
• יְלָדִים טוֹבִים = good boys
• הַיְלָדִים הַטּוֹבִים = the good boys

Attributive vs. Predicative

The position of הַ changes the meaning completely:
• הַיֶּלֶד הַגָּדוֹל = the big boy (attributive - describes which boy)
• הַיֶּלֶד גָּדוֹל = the boy is big (predicative - a sentence, no הַ on adjective)

In Sentences

יֵשׁ לִי סֵפֶר חָדָשׁ
yesh li SE-fer kha-DASH
I have a new book
indefinite - no הַ on either
הַמּוֹרָה הַחֲדָשָׁה נֶחְמָדָה
ha-mo-RA ha-kha-da-SHA nekh-ma-DA
The new teacher (f.) is nice
definite noun + definite adjective
הַבָּתִּים הַיְשָׁנִים יָפִים
ha-ba-TIM ha-ye-sha-NIM ya-FIM
The old houses are beautiful
plural definite + predicative adjective
אֲנִי רוֹצֶה כֶּלֶב קָטָן
a-NI ro-TSE KE-lev ka-TAN
I want a small dog
indefinite masculine

Quick Tip

Think of it as a checklist - every adjective must match its noun in three things: gender (m/f), number (sg/pl), and definiteness (with or without הַ).
