The best I can think of is a VARRAY, though you cannot access
it by index in SQL (you need a stored procedure or client API
for that). Quite clumsy.

Example:

SQL> CREATE TYPE VARCHAR_A AS VARRAY(100) OF VARCHAR2(10);
2 /

Type created.

SQL> CREATE TABLE N(ID NUMBER(10,0) PRIMARY KEY, A VARCHAR_A);

Table created.

SQL> INSERT INTO N VALUES (1, VARCHAR_A('one', 'two', 'three'));

1 row created.

SQL> SELECT A FROM N WHERE ID=1;

A
------------------------------------------------------------------------
--------
VARCHAR_A('one', 'two', 'three')

SQL> SELECT X.* FROM N, TABLE(N.A) X WHERE ID=1;

COLUMN_VALUE
----------------------------------------
one
two
three
